ML33111

Low Voltage Compander

Silicon Monolithic Integrated Circuit

Legacy Device:

Motorola MC33111

The ML33111 contains two variable gain circuits configured for compress-

ing and expanding the dynamic range of an audio signal. One circuit is config-

ured 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 tempera-

ture stable bandgap reference provides the necessary precision voltages.

Included in the ML33111 are controls for muting each section independ-

ently, and for pass through of both. Two uncommitted op amps are available

for peripheral functions.

The ML33111 will operate from a supply voltage of 3.0 V to 7.0 V and

over a temperature range of TA –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.
