SSM2122 - (SSM2120 / SSM2122) Dynamic Range Processors/Dual VCA

General Description

V

The SSM2120 is a monolithic integrated circuit designed for the purpose of processing dynamic signals in various analog systems including audio.

This “dynamic range processor” consists of two VCAs and two level detectors (the SSM2122 consists of two VCAs only).

Key Features

  • 0.01% THD at +10 dBV In/Out 100 dB VCA Dynamic Range Low VCA Control Feedthrough 100 dB Level Detection Range Log/Antilog Control Paths Low External Component Count.
