Advance Information
Low Voltage Compander
The MC33111 contains two variable gain circuits configured for
compressing and expanding the dynamic range of an audio signal. 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.
The MC33111 will operate from a supply voltage of 3.0 V to 7.0 V, and
over a temperature range of – 40° to + 85°C. It is designed to
accommodate a 60 dB dynamic range; from – 40 dB to + 20 dB referenced
to 100 mVrms.
Applications include cordless telephone, CBs, walkie-talkies, and most
voice RF links, and any application where an improvement in the signal to
noise ratio is desired. Other applications include speakerphones and voice
activated intercoms, dictating machines, etc.
Operating Supply Voltage: 3.0 V to 7.0 V
Output Voltage Swing = 2.8 Vp-p with VCC = 3.0 V
No Precision External Components Required
60 dB Dynamic Range Compressed to 30 dB, Re-expandable to 60 dB
