... Audio ICs Sound control IC BH3852S / BH3852FS The BH3852S and BH3852FS are signal processing ICs designed for volume and tone control in CD radio cassettes and other audio products. They can be used without a microcomputer because they use DC current for control. FApplications CD radio cassettes, micro components, car stereos, tele- ...
