The THAT2181 voltage controlled amplifier(VCA) is a high performance current in/current out device with two opposing polarity, voltage sensitive control ports.

It offers wide range exponential control of gain and attenuation with lower signal distortion.

The parts are selected after packaging and the selection is based primarily on after-trim THD and control voltage feedthrough performance.

The VCA design takes advantage of a fully complementary dielectric isolation process which offers closely matched NPN/PNP pairs. This delivers performance unobtainable through any conventional process, integrated or discrete.

The part is user trimmable to a minimum of 0.005% THD allowing the user to optimise cost and performance.

Demonstration Board THAT2181DEMO is available for this product.
