LC75343M Description
ENN6867 CMOS IC LC75343M Electronic Volume Control System on-Chip Overview The LC75343M is an electronic volume system that can control the volume, balance, 2-band equalizer, super bass, and input switching functions by serial data input. Regarding (Bass) and (Super bass) above, MID and BASS functions can also be realized by changing the capacitor capacitance.
