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.
