SA2159

SA2159 VOLTAGE CONTROLLED AMPLIFIER FOR ELECTRONIC VOLUME CONTROL DESCRIPTION The SA2159 is a voltage-controlled amplifier (VCA) circuit. The chip is a high-performance current– in/current-out devices including two opposingpolarity, voltage-sensitive control ports. Due to super low-noise application, the circuit adopts high hFE. Complementary NPN/PNP pairs configuration. It requires little external support circuitry and selects a space-efficient plastic 8-pin single– in– line (SIP) package. The SA2159 VCA combines a number of advantages such as low noise, low distortion, low offset and high gain-bandwidth to offer discrete performance at IC prices.
