Austriamicrosystems unveils AS1713 amplifier

Austriamicrosystems, a designer and manufacturer of high-performance analogue ICs, has introduced the AS1713 operational amplifier, a high-output differential line receiver.

With a 10MHz, 10V/us, rail-to-rail input/output (I/O) performance, the device is said to be suitable for audio applications such as headphone drivers and audio line receivers and buffers.

The AS1713 operational amplifier operates from a single +2.7V to +5.5V supply and can swing to within 100mV from the rails while sinking or sourcing 50mA of output current.

Large short-time loads, common in various applications such as in audio amplification, are supported by a peak output current of more than 200mA.

The AS1713 requires 1.6mA of supply current and 1nA while in shutdown.

Internal matched resistors reduce external component count and costs.

The company claims that flexible interconnections support external gain setting and adjustments in other applications.

In addition, 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 classic three-amplifier instrument amplifier (IA) structure.
