One circuit is configured as an expander, and the other is configured as a compressor. Each circuit has a full wave rectifier to provide average value information to a variable gain cell located in either the input stage or the feedback path. An internal temperature stable bandgap reference provides the necessary precision voltages. Included in the MC33111 are controls for muting each section independently, and for passthrough of both. Two uncommitted op amps are available for peripheral functions.
