Compander IC MM1102
Compander IC
Monolithic IC MM1102
Features
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.
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
