opa347, 2347, 4347 7 sbos167d www.ti.com applications information the opa347 series op amps are unity-gain stable and can operate on a single supply, making them highly versatile and easy to use. rail-to-rail input and output swing significantly increases dy- namic range, especially in low supply applications. figure 1 shows the input and output waveforms for the opa347 in unity-gain configuration. operation is from v s = +5v with a 100k ? load connected to v s /2. the input is a 5v pp sinusoid. output voltage is approximately 4.995v pp . power-supply pins should be bypassed with 0.01 f ceramic capacitors. operating voltage the opa347 series op amps are fully specified and en- sured from 2.5v to 5.5v. in addition, many specifications apply from 55 c to +125 c. parameters that vary signifi- cantly with operating voltages or temperature are shown in the typical characteristics. rail-to-rail input the input common-mode voltage range of the opa347 series extends 200mv beyond the supply rails. this is achieved with a complementary input stage an n-channel input differential pair in parallel with a p-channel differential pair, as shown in figure 2. the n-channel pair is active for input voltages close to the positive rail, typically (v+) 1.3v to 200mv above the positive supply, while the p-channel pair is on for inputs from 200mv below the negative supply to approximately (v+) 1.3v. there is a small transition region, typically (v+) 1.5v to (v+) 1.1v, in which both pairs are on. this 400mv transition region can vary 300mv with process variation. thus, the transition region (both stages on) can range from (v+) 1.65v to (v+) 1.25v on the low end, up to (v+) 1.35v to (v+) 0.95v on the high end. within the 400mv transition region psrr, cmrr, offset voltage, and offset drift may be degraded compared to operation outside this region. for more information on de- signing with rail-to-rail input op amps, see figure 3, design optimization with rail-to-rail input op amps . figure 2. simplified schematic. figure 1. rail-to-rail input and output. v bias1 v bias2 v in + v in class ab control circuitry v o v (ground) v+ reference current input output (inverted on scope) 5v 1v/div 0v g = +1, v s = +5v 20 s/div
opa347, 2347, 4347 8 sbos167d www.ti.com common-mode rejection the cmrr for the opa347 is specified in several ways so the best match for a given application may be used. first, the cmrr of the device in the common-mode range below the transition region (v cm < (v+) 1.7v) is given. this specifica- tion is the best indicator of the capability of the device when the application requires use of one of the differential input pairs. second, the cmrr at v s = 5.5v over the entire common-mode range is specified. input voltage the input common-mode range extends from (v ) 0.2v to (v+) + 0.2v. for normal operation, inputs should be limited to this range. the absolute maximum input voltage is 500mv beyond the supplies. inputs greater than the input common-mode range but less than the maximum input voltage, while not valid, will not cause any damage to the op amp. furthermore, if input current is limited the inputs may go beyond the power supplies without phase inversion, as shown in figure 4, unlike some other op amps. normally, input currents are 0.4pa. however, large inputs (greater than 500mv beyond the supply rails) can cause excessive current to flow in or out of the input pins. there- fore, as well as keeping the input voltage below the maxi- mum rating, it is also important to limit the input current to less than 10ma. this is easily accomplished with an input resistor, as shown in figure 5. figure 3. design optimization with rail-to-rail input op amps. rail-to-rail op amps can be used in virtually any op amp configuration. to achieve optimum performance, how- ever, applications using these special double-input-stage op amps may benefit from consideration of their special behavior. in many applications, operation remains within the com- mon-mode range of only one differential input pair. how- ever, some applications exercise the amplifier through the transition region of both differential input stages. a small discontinuity may occur in this transition. careful selection of the circuit configuration, signal levels, and biasing can often avoid this transition region. design optimization with rail-to-rail input op amps with a unity-gain buffer, for example, signals will traverse this transition at approximately 1.3v below the v+ supply and may exhibit a small discontinuity at this point. the common-mode voltage of the noninverting amplifier is equal to the input voltage. if the input signal always remains less than the transition voltage, no discontinuity will be created. the closed-loop gain of this configuration can still produce a rail-to-rail output. inverting amplifiers have a constant common-mode volt- age equal to v b . if this bias voltage is constant, no discontinuity will be created. the bias voltage can gener- ally be chosen to avoid the transition region. figure 4. opa347 no phase inversion with inputs greater than the power-supply voltage. v o v in v b v+ noninverting amplifier v cm = v in v o v b v in v+ inverting amplifier v cm = v b v o v in v+ unity-gain buffer v cm = v in = v o figure 5. input current protection for voltages exceeding the supply voltage. 5k ? opa347 10ma max +5v v in v out i overload 5.5v 0v 0.5v 200 s/div
opa347, 2347, 4347 9 sbos167d www.ti.com rail-to-rail output a class ab output stage with common-source transistors is used to achieve rail-to-rail output. this output stage is ca- pable of driving 5k ? loads connected to any potential be- tween v+ and ground. for light resistive loads (> 100k ? ), the output voltage can typically swing to within 5mv from supply rail. with moderate resistive loads (10k ? to 50k ? ), the output can swing to within a few tens of millivolts from the supply rails while maintaining high open-loop gain (see the typical characteristic output voltage swing vs output current). capacitive load and stability the opa347 in a unity-gain configuration can directly drive up to 250pf pure capacitive load. increasing the gain en- hances the amplifier s ability to drive greater capacitive loads (see the characteristic curve small-signal overshoot vs capacitive load). in unity-gain configurations, capacitive load drive can be improved by inserting a small (10 ? to 20 ? ) resistor, r s , in series with the output, as shown in figure 6. this significantly reduces ringing while maintaining direct current (dc) performance for purely capacitive loads. how- ever, if there is a resistive load in parallel with the capacitive load, a voltage divider is created, introducing a dc error at the output and slightly reducing the output swing. the error introduced is proportional to the ratio r s /r l , and is generally negligible. load, reducing the resistor values from 100k ? to 5k ? de- creases overshoot from 40% to 8% (see the characteristic curve small-signal overshoot vs load capacitance). how- ever, when large-valued resistors can not be avoided, a small (4pf to 6pf) capacitor, c fb , can be inserted in the feedback, as shown in figure 7. this significantly reduces overshoot by compensating the effect of capacitance, c in , which includes the amplifier input capacitance and pc board parasitic capacitance. figure 6. series resistor in unity-gain buffer configura- tion improves capacitive load drive. 10 ? to 20 ? opa347 v+ v in v out r s r l c l figure 7. adding a feedback capacitor in the unity-gain inverter configuration improves capacitative load. r i opa347 v in v out r f c fb c in c l driving adcs the opa347 series op amps are optimized for driving medium-speed sampling analog-to-digital converters (adcs). the opa347 op amps buffer the adc s input capacitance and resulting charge injection while providing signal gain. see figure 8 for the opa347 in a basic noninverting configu- ration driving the ads7822. the ads7822 is a 12-bit, micro power sampling converter in the msop-8 package. when used with the low-power, miniature packages of the opa347, the combination is ideal for space-limited, low- power applications. in this configuration, an rc network at the adc input can be used to provide for anti-aliasing filter and charge injection current. see figure 9 for the opa2347 driving an ads7822 in a speech bandpass filtered data acquisition system. this small, low-cost solution provides the necessary amplification and signal conditioning to interface directly with an electret micro- phone. this circuit will operate with v s = 2.7v to 5v with less than 250 a typical quiescent current. in unity-gain inverter configuration, phase margin can be reduced by the reaction between the capacitance at the op amp input, and the gain setting resistors, thus degrading capacitive load drive. best performance is achieved by using small valued resistors. for example, when driving a 500pf

(2) recommended solder paste is type 3 or type 4. (3) best reliability results are achieved when the pwb laminate glass transistion temperature is above the operating range of the intended application. (4) for pwb using an ni/au surface finish, the gold thickness should be less than 0.5um to avoid solder embrittlement and a reduction in thermal fatigue performan ce. (5) solder mask thickness should be less than 20um on top of the copper circuit pattern. (6) best solder stencil performance will be achieved using laser -cut stencils with electro polishing. use of chemically etched stencils results in inferior solder paste volume control.
