THAT 2181 Series integrated-circuit voltage controlled amplifiers (VCAs) are very high performance current-in/current-out devices with two opposing-polarity, voltage-sensitive control ports. They offer wide-range exponential control of gain and attenuation with low signal distortion. The parts are trimmed at wafer stage for low THD and control-voltage feedthrough without further adjustment.
The VCA design takes advantage of a fully complementary dielectric isolation process which offers closely matched NPN/PNP pairs, to deliver discrete performance at IC prices. The 2180 Series is available in an 8-pin single-in-line (SIP) package.
