IC for Headphone Stereos
Monolithic IC MM1006
Outline
This IC was developed for use in headphone stereos, and incorporates the basic functions of a tape player as
well as dual preamp, power amp, and motor control circuits. It requires few external components and can be
used in a simple circuit configuration.
Features
1. Broad operating voltage range of 2.0 to 5.0 V (amp system operates to 1.8 V)
2. Simple circuit configuration
3. Power amp fixed at 28 dB
4. Ripple filter included
5. Provided with pin to turn off preamps
6. With noise from motor driving unit suppressed
