DESCRIPTION
THAT 2181-series trimmable Blackmer voltage-controlled amplifier (VCA) ICs 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 selected after packaging based primarily on after-trim THD and control-voltage feedthrough performance. In-circuit adjustment is required to achieve the guaranteed distortion and feedthrough performance.
