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). These circuit blocks allow the user to logarithmically control the gain or attenuation of the.
