1999 apr 08 8 philips semiconductors product speci?cation speech and loudspeaker ampli?er ic with auxiliary inputs/outputs and analog multiplexer tea1097 the preferred value for r slpe is 20 w . changing this value will affect more than the dc characteristics; it also influences the transmit gains to the line, the gain control characteristic, the sidetone level and the maximum output swing on the line. as can be seen from fig.4, the internal circuitry is supplied by pin v bb , which is a strong supply point combined with the line interface. the line current is flowing through the r slpe resistor and is sunk by the v bb voltage stabilizer, becoming available for a loudspeaker amplifier or any peripheral ic. its voltage is equal to 3.0 v for line currents lower than 18 ma. it than increases linearly with the line current and reaches the value of 5.3 v for line currents greater than 45 ma. it is temperature compensated. the aim of the current switch tr1 and tr2 is to reduce distortion of large ac line signals. current i slpe is supplied to v bb via tr1 when the voltage on slpe is greater than v bb + 0.25 v. when the voltage on slpe is lower than this value, the current i slpe is shunted to gnd via tr2. the reference voltage v ref can be increased by connecting an external resistor between pins reg and slpe. for large line currents, this increase can slightly affect some dynamic performances such as maximum signal level on the line for 2% thd. the voltage on pin v bb is not affected by this external resistor. see fig.5 for the main dc voltages. fig.4 line interface principle. handbook, full pagewidth mgm298 tn2 tr2 tr1 e2 d1 d1 r3 r2 r1 tn1 tp1 j2 j1 e1 gnd gnd v bb from preamp gnd reg ln slpe c reg 4.7 m f r slpe 20 w

1999 apr 08 12 philips semiconductors product speci?cation speech and loudspeaker ampli?er ic with auxiliary inputs/outputs and analog multiplexer tea1097 e arpiece amplifier ( pins garx and qr) the earpiece amplifier is an operational amplifier having its output (qr) and its inverting input (garx) available. its input signal comes, via a decoupling capacitor, from the receive reco output. it is used in combination with two resistors to get the required gain or attenuation compared to the receive gain. it can be chosen between - 3 and +15 db. two external capacitors c gar (connected between pins garx and qr) and c gars (connected between pins garx and gnd) ensure stability. the c gar capacitor provides a first-order low-pass filter. the cut-off frequency corresponds to the time constant c gar r e2 . the relationship c gars 3 10 c gar must be fulfilled. the earpiece amplifier has a rail-to-rail output qr, biased at two diodes voltage. it is designed for use with low-ohmic (real) loads (150 w ) or capacitive loads (100 nf in series with 100 w ). when the amplifier is turned off, the signal present on the earpiece is equal to the ratio between the load on qr and r e1 +r e2 a uxiliary receive amplifier ( pins raux and reco) the auxiliary receive amplifier has an asymmetrical input raux; it uses the reco output. its input impedance between pins raux and gnd is typically equal to 20 k w . the voltage gain between pins raux and reco is equal to - 2.4 db. without any limitation from the output, the input stage can accommodate signals up to 0.95 v (rms) at room temperature for 2% of thd. this auxiliary amplifier has a rail-to-rail output reco, which is designed for use with high ohmic (real) loads (larger than 5 k w ). this output is biased at two diodes voltage. the automatic gain control has no effect on this channel. auxiliary ampli?ers using auxo (pins mic+, mic - , hftx, ir and auxo) the tea1097 has an auxiliary output auxo, biased at two diodes voltage. this output stage is a rail-to-rail one, designed for use with high-ohmic (real) loads (larger than 5k w ). the auxo output amplifier is used in three different channels, two transmit channels and one receive channel. a uxiliary amplifiers using the microphone inputs ( pins mic+, mic - and auxo) the auxiliary transmit amplifier using the microphone mic+ and mic - inputs has a gain of 25.5 db referenced to auxo. without limitation from the output, the input stage can accommodate signals up to 16 mv (rms) at room temperature for 2% of thd. the automatic gain control has no effect on this channel. a uxiliary amplifiers using hftx ( pins hftx and auxo) the auxiliary transmit amplifier using the hftx input has a gain of 15.2 db referenced to auxo. the automatic gain control has no effect on this channel. rx amplifier using ir ( pins ir and auxo) the auxiliary receive amplifier uses pin ir as input. the input is referenced to pin ln and the dc biasing between these two pins is one diode voltage. the voltage gain between the input ir (referenced to ln) and the output auxo is typically equal to 32.8 db, which compensates typically the attenuation provided by the anti-sidetone network. automatic gain control is provided for line loss compensation. automatic gain control (pin agc) the tea1097 performs automatic line loss compensation, which fits well with the true line attenuation. the automatic gain control varies the gain of some transmit and receive amplifiers in accordance with the dc line current. the control range is 6.45 db for g v(mic-ln) , g v(ir-reco) and g v(ir-auxo) and 6.8 db for g v(txaux-ln) , which corresponds approximately to a line length of 5.5 km for a 0.5 mm twisted-pair copper cable. to enable this gain control, the pin agc must be shorted to pin ln. the start current for compensation corresponds to a line current equal to typically 23 ma and the stop current to 57 ma. the start current can be increased by connecting an external resistor between pins agc and ln. it can be increased to 40 ma (using a resistor typically equal to 80 k w ). the start and stop current will be maintained in a ratio equal to 2.5. by leaving the agc pin open-circuit, the gain control is disabled and no line loss compensation is performed.

1999 apr 08 31 philips semiconductors product speci?cation speech and loudspeaker ampli?er ic with auxiliary inputs/outputs and analog multiplexer tea1097 soldering introduction to soldering surface mount packages this text gives a very brief insight to a complex technology. a more in-depth account of soldering ics can be found in our data handbook ic26; integrated circuit packages (document order number 9398 652 90011). there is no soldering method that is ideal for all surface mount ic packages. wave soldering is not always suitable for surface mount ics, or for printed-circuit boards with high population densities. in these situations reflow soldering is often used. re?ow soldering reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. several methods exist for reflowing; for example, infrared/convection heating in a conveyor type oven. throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. typical reflow peak temperatures range from 215 to 250 c. the top-surface temperature of the packages should preferable be kept below 230 c. wave soldering conventional single wave soldering is not recommended for surface mount devices (smds) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. to overcome these problems the double-wave soldering method was specifically developed. if wave soldering is used the following conditions must be observed for optimal results: use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. for packages with leads on two sides and a pitch (e): C larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; C smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves at the downstream end. for packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. the footprint must incorporate solder thieves downstream and at the side corners. during placement and before soldering, the package must be fixed with a droplet of adhesive. the adhesive can be applied by screen printing, pin transfer or syringe dispensing. the package can be soldered after the adhesive is cured. typical dwell time is 4 seconds at 250 c. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. manual soldering fix the component by first soldering two diagonally-opposite end leads. use a low voltage (24 v or less) soldering iron applied to the flat part of the lead. contact time must be limited to 10 seconds at up to 300 c. when using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 c.
1999 apr 08 32 philips semiconductors product speci?cation speech and loudspeaker ampli?er ic with auxiliary inputs/outputs and analog multiplexer tea1097 suitability of surface mount ic packages for wave and re?ow soldering methods notes 1. all surface mount (smd) packages are moisture sensitive. depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). for details, refer to the drypack information in the data handbook ic26; integrated circuit packages; section: packing methods . 2. these packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink (at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version). 3. if wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. the package footprint must incorporate solder thieves downstream and at the side corners. 4. wave soldering is only suitable for lqfp, tqfp and qfp packages with a pitch (e) equal to or larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 5. wave soldering is only suitable for ssop and tssop packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. definitions life support applications these products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. philips customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify philips for any damages resulting from such improper use or sale. package soldering method wave reflow (1) bga, sqfp not suitable suitable hlqfp, hsqfp, hsop, htssop, sms not suitable (2) suitable plcc (3) , so, soj suitable suitable lqfp, qfp, tqfp not recommended (3)(4) suitable ssop, tssop, vso not recommended (5) suitable data sheet status objective speci?cation this data sheet contains target or goal speci?cations for product development. preliminary speci?cation this data sheet contains preliminary data; supplementary data may be published later. product speci?cation this data sheet contains ?nal product speci?cations. limiting values limiting values given are in accordance with the absolute maximum rating system (iec 134). stress above one or more of the limiting values may cause permanent damage to the device. these are stress ratings only and operation of the device at these or at any other conditions above those given in the characteristics sections of the speci?cation is not implied. exposure to limiting values for extended periods may affect device reliability. application information where application information is given, it is advisory and does not form part of the speci?cation.
