FUNCTIONAL DESCRIPTION
TDA1551Q
The TDA1551Q contains four identical amplifiers with differential input stages (two inverting and two non-inverting) which can be used in SE or BTL applications. The gain of each amplifier is fixed at 20 dB for SE and 26 dB for BTL. The device also contains an I2C-bus facility which operates in the read or write mode. In the write mode the device can be switched to either the sleep condition (low sleep current of 0.6 mA typ.), the MUTE condition or the ON condition. In the read mode an 8-bit status word is available. Data bits D0 to D3 contain status information of each of the 4 outputs. If the device is switched to the ON or MUTE condition and there is a short-circuit at one or more outputs, the power transistors will be outside their safe operating area consequently one or more bits of D0 to D3 will be HIGH. Bits D0 to D3 are LOW when in the normal safe operating area. Bit D4 is normally LOW if one or more channels reaches the clipping level D4 will go HIGH. Bit D5 is normally LOW, if the crystal temperature reaches 150 C D5 will go HIGH. After a power-on reset bit 7 will go HIGH and a dip in the power supply will be noticed. Bit 7 will go LOW after the I2C-bus is read. When pin 9 is LOW the device will switch OFF and the supply current will be reduced to 0.1 mA (max.).

To get into the ON condition without switch-on plops, the device should be switched from the SLEEP condition to the MUTE condition and then, after a period of 150 ms, to the ON condition. Bit D0 switches from SLEEP to the ON condition Bit D1 switches the MUTE condition

SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). Soldering by dipping or by wave The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds.
TDA1551Q
The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. Repairing soldered joints Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 C, contact may be up to 5 seconds.

TDA1551Q
This data sheet contains target or goal specifications for product development. This data sheet contains preliminary data; supplementary data may be published later. This data sheet contains final product specifications.
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 specification 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 specification. 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. PURCHASE OF PHILIPS I2C COMPONENTS
Purchase of Philips I2C components conveys a license under the Philips' I2C patent to use the components in the I2C system provided the system conforms to the I2C specification defined by Philips. This specification can be ordered using the code 9398 393 40011.
