The THAT2180BL08-U is a Blackmer? pre-trimmed IC voltage controlled Amplifier 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 feed through without further adjustment. The VCA design takes advantage of a fully complementary dielectric isolation process which offers closely matched NPN/PNP pairs.
