This amplifier operates over a w ide range of power o supply voltages, with little change in per for mance characteristics .At 25 C amplifier operation is possible down to a minimum supply voltage of 3V. Large differential input voltage can be easily accommodates and, as input differential voltage protection diodes are not needed, no large input currents result from large differ ential input voltage. The differential input voltage may be larger + than V without damaging the dev ice. Protec tion should be provided to prevent the input voltage from going negative o more than –0.3 VDC (at 25 C). An input c lamp diode with a resis tor to the IC input ter minal can be used. To r educe the power supply drain, the amplifier has a class A output stage for s mall signal levels w hich converts to class B in a large signal mode. This allows the amplifiers to both source and sink large output currents . Therefore both NPN and PNP ex ternal current boots transistor can be used to extend the power capability of the basic amplifiers. The output voltage needs to raise approximately 1 diode dr op above ground to bias the on-chip ver tical PN P tr ansistor for output current sinking applications. For AC applications , where the load is capacitively coupled to the output of the amplifier, a resistor should be used, from the output of the amplifier to ground to increase the class A bias current and to reduce dis tortion. C apacitive loads which are applied direc tly to the output of the amplifier reduce the loop s tability margin. Values of 50pF can be accommodated using the worst-case non- inverting unity gain connec tion. Large closed loop gains or res istive isolation should be used if large load capac itance must be driven by the amplifier The bias network of the TS312 establishes a supply current which is independent of the magnitude of the magnitude of the power supply voltage over the range of from 3VDC to 3VDC. Output shor t circuits either to ground or to the positive power supply should be of short time duration. U nits can be destroyed , not as a result of the short circuit current causing metal fusing, but rather due to the large increase in IC chip dissipation which cause eventual failure due to ex cessive junc tion temperatures. The large value of output source o current w hich is available at 25 C , prov ides a large output current capability at elevated temperature than a s tandard IC op amp. The circuits presented in the section on typical applic ations emphasize operation on only a single power supply voltage. If complementary power supplies are available, all of the standard op amp circuits can be used. In general, introducing + a pseudo-ground (a bias voltage reference of V /2) will allow operation above and below this value in single power supply systems . Many application c ircuits are shown which take advantage of the wide input common- mode voltage range which includes ground. In most cases , input bias ing is not required and input voltage which range to gr ound can easily be accommodated. Typical Applications Fi gure 1. LED Driver Fi gure 2.
