BH3863F/BH3863S
The BH3863F/BH3863S is a sound control IC for mini-component stereo. Resistive ladder system is used to make DC
offset smaller when switching. This IC is a 2-wire serial controller.
Small package of SOP24 and SDIP24 is adopted.
!
Applications
Mini-component stereo, Micro-component stereo, TV and CD radio cassette tape player
!
Features
1) Volume, tone and bass boost can be controlled through serial control from a microcomputer.
2) Volume at both left and right sides can be controlled individually.
3) Resistive ladder type volume controller is used and BiCMOS process enables the low distortion rate and low noise.
4) It has a dynamic bus for the low frequency reinforcement.
