Outline
This IC was developed to provide bass boost functions without deviating from the basic design concept of Mitsumi's LAG665, which is highly regarded for applications in headphone stereos for overseas markets in
particular.
FEATUREs
1. Configuration: pre and power amps, motor control, E. VR, bass boost
2. Preamp off function convenient for use in models with radios
3. Independent motor control circuit
1. Motor noise is effectively suppressed
2. With motor on/off pin (motor can be stopped easily when radio is in use)
3. With fast forward pin
4. Bass boost frequency characteristic can be changed simply by changing the resistance multiplier.
5. Well-balanced E. VR circuit
1. L, R channels variable using a single VR
2. A-curve can be reproduced using B-curve VR
6. Few external components
