THAT2181C

The THAT2181C is an integrated-circuit Voltage Controlled Amplifier has very high-performance current-in/current-out devices with two opposing-polarity, voltage-sensitive control ports. It offers wide-range exponential control of gain and attenuation with low signal distortion. The parts are selected after packaging based primarily on after-trim THD and control-voltage feed-through 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.
