Compander IC MM1102

Compander IC

Monolithic IC MM1102

This IC was developed for use in cordless telephones. 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. Internal mute function

3. Internal limiter (IDC) function

4. Two internal op-amps (for splatter filter)

5. Internal standby function

6. Data input, output pins

7. Independent mute circuit

Package
