THAT 2181 Series integrated-circuit voltage controlled amplifiers (VCAs) THAT2181C 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 THAT2181C parts are selected after packaging based primarily on after-trim THD and control- voltage feedthrough performance.

The VCA THAT2181C design takes advantage of a fully complementary dielectric isolation process which offers closely matched NPN/PNP pairs. This THAT2181C delivers performance unobtainable through any conventional process, integrated or discrete. The THAT2181C parts available in three grades, allowing the user to optimize cost vs. performance. Both 8-pin single-in-line (SIP) and surface mount (SO) packages are available.
