The MC33110 contains two variable gain circuits configured for

compressing and expanding the dynamic range of an audio signal. One

circuit is configured as an expander, while the other circuit can be configured

as a compressor or expander. 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 and currents required.

The MC33110 will operate from a supply voltage of 2.1 to 7.0 V, over a

temperature range of –40 to 85°C. The device is designed to accommodate

an 80 dB dynamic range from –60 dB to 20 dB, referenced to 100 mVrms.

Applications include cordless telephone, CB, walkie–talkie, most voice

RF links, and any application where the signal–to–noise ratio can be

improved by reducing the transmitted dynamic range. Other applications

include speakerphone and voice activated intercom, dictating machine,

standard telephone, etc.
