Compander IC MM1077
Compander IC
Monolithic IC MM1077
Outline
This IC was developed for use in cordless telephone 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 2.0V)
2. Internal mute function
3. Internal limiter (IDC) function
4. Compressor input can be switched between MIC and LINE
5. Internal standby function
6. Data input, output pins
7. Independent mute circuit
Package
SSOP-24A (MM1077XF)
Applications
1. Cordless telephones
2. Various mobile communication devices
