This audio compander circuit schematic is equiped with NE575 produced by Signetics, it is working with a 3 – 7V battery and has a current consumption of 3.5mA at 3V and 5mA at 7V. The companding process ( input compression, output as expander) is improving the signal/noise ratio on a communication line.

But the simple circuit expander compressor shown here provides a low-cost solution. Constructed with a few passive components, it can give surprisingly good results. The circuit expander compressor furnishes both the functions-compression and expansion (often expressed by the term compander)-easily. The expander compressor uses an opto-isolator.

COMPANDER Description The V571D/M is a versatile low cost dual gain control circuit in which either channel may be used as a dynamic range compressor or expandor. Each channel has a full-wave rectifier to detect the average value of the signal, a linerarized temperature-compensated variable gain cell, and an operational amplifier.

A Compander is a non-linear circuit which provides high amplification for low input amplitude signals and low amplification for high input amplitude signals. A compander operates in a transmitter to compress audio signals before they are transmitted and in a receiver to expand the audio signals after they are received.

The compressor is the part that makes quiet signals louder (“compresses the dynamic range” in the jargon) and then the expander reverses the process and makes them quiet again (expands the dynamic range). Obviously it’s important that the two stages cancel each other out if we want the overall dynamics of the signal not to get mangled.

Oct 18, 2017. #3. The MC33110 is obsolete and is not made anymore. It was never designed for PWM, it was designed to compress and expand analog audio like the old Philips compander ICs did. I hate to hear an FM station compress the audio so that the background music level changes with the bass beat of the music.
