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.
