Outline
This IC was developed for use in 3 V headphone stereos. It incorporates dual preamp, power amp, electronic volume and motor control circuits; because it requires extremely few external components, it can be used in a simple circuit configuration.

FEATUREs
1. Broad operating voltage range of 2.0 to 5.0 V
2. Few external components required
3. Well-balanced electronic VR, A-curve attenuation characteristic obtained with B-curve VR
4. Internal motor control circuit, with noise from motor driving unit suppressed
5. Fast forward possible using the forced-on pin
