Differential amplifier

The AS1713 op-amp is suitable for applications such as headphone drivers, where the operating environment demands built-in rejection of ground interference. Other applications include infotainment high drive audio line receivers and buffers.

The austriamicrosystems AS1713 operational amplifier has a 10 MHz, 10 V/µs, rail-to-rail I/O performance.

It operates from a single +2.7 to +5.5 V supply and can swing to within 100 mV from the rails while sinking or sourcing 50 mA of output. Large short time loads are supported by a peak output of \>200 mA. The device requires 1.6 mA of supply and 1 nA while in shutdown mode,

It has a fixed differential voltage gain of 1. Internal matched resistors reduce external component count and costs. Flexible interconnections support external gain setting and adjustments in other applications.

The trimmed resistor network allows the part to be used as a low-cost, general-purpose instrumentation amplifier. Gain and impedance conversion may be provided by adding an external dual amplifier to create the three amplifier IA (instrument amplifier) structure.
