VOLTAGE CONTROLLED AMPLIFIER FOR ELECTRONIC VOLUME CONTROL

SIP-8

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

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.

FEATURES

* Wide dynamic range:>115dB

* Wide gain range:>130dB

* Logarithmic gain control

* Low distortion:(0.008%@0dB gain, 0.035%@15dB gain)

* Wide gain-bandwidth: 6MHz

* Single in–line package

* Dual gain-control ports(pos/neg)
