IC for Headphone Stereos (with volume-limiting circuit) MM1336
IC for Headphone Stereos (with volume-limiting circuit)
Monolithic IC MM1336
Outline
This IC was developed for use in 3V headphone stereos. In addition to the basic functions required by
headphone stereos, it incorporates a circuit for limiting volume. In some parts of Europe hearing impairment
caused by the high volumes of headphone stereos has become a problem, and there has been strong
demand for functions for limiting loud volumes in the sets themselves. This trend is expected to gain
momentum in the U.S. as well.
This IC uses an internal ALC circuit to suppress headphone stereo output, avoiding the above problem.
Features
1. Configuration: Pre-and power amps, ALC circuit, motor control
2. Internal tape selector: A selector switch allows the user to select between normal and metal tapes.
3. Internal OCL circuit: There is no need for a capacitor for high-volume output, so sets can be kept thin.
4. With preamp off pin while connected to radio
5. Designed for low shock noise
Reduced noise occuring when the power supply is turned on and off
