Description
THAT 2180 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 parts are available in three grades, selected for factory trimmed distortion, alowing the user to optimize cost vs. performance. The 2180 Series is available in an 8-pin single-in-line (SIP) package.
