THAT2181A Description
THAT 2181 Series integrated-circuit voltage controlled amplifiers (VCAs) are very highperformance 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 selected after packaging based primarily on after-trim THD and control-voltage feedthrough performance.
