IC for Headphone Stereos
Monolithic IC MM1104
Outline
This IC was developed for use in 3 V headphone stereos. It incorporates all the basic functions of tape
players.
Mitsumi has previously offered the LAG665, LAG668, LAG673 and MM1006 as one-chip versions. However,
this IC is the result of a through review and redesign extending to circuit details.
Features
1. Configuration: Pre-and power amp, motor control
2. Adoption of shock noise prevention circuitry
Through the use of a circuit which suppresses noise occurring when the power supply is turned on and off,
noise output is reduced without muting.
3. Stable motor speed control circuit
A bridge circuit employing power transistors provides motor speed control with minimal drift.
4. Preamp off pin is convenient for radio connections
5. Radiation pin: When radio wave-induced noise is a problem, this pin can be used to cut the frequency
characteristic.
