IC for Headphone Stereos (bass boost) LAG668
IC for Headphone Stereos (bass boost)
Monolithic IC LAG 668
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.
Bass boost functions are widely adopted in models for overseas markets as well. However, because of
stringent cost constraints, there has been a need for an IC which is simple and inexpensive. This IC can
provide bass boost functions simply by adding three resistors and one capacitor (per channel).
Moreover, it has the same pinout as the LAG665, so that by making selective use of set features, a product
lineup can be developed without changes to the printed circuit board.
Features
Package
Absolute Maximum Ratings
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
