Monolithic IC MM1100

Outline

This IC was developed for use in mobile communication equipment. It is a compander IC incorporating
compressor/expander circuits for a significant noise reduction effect without complicated external circuitry.
On the transmission side, the dynamic range of audio signals is compressed by the compressor circuit; on the
receiving side, the expander expands the signals. As a result the dynamic range over the transmission
channel is reduced logarithmically by one-half.

Features

1. Can be driven at low voltages (down to 2.4V)

2. Compression and expansion circuits enable suppression of unwanted radio waves

3. Consumption current 2.8mA typ.
