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 opposing-
polarity, 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.
