LC75421M Datasheet | SANYO

Ordering number : ENN6866A CMOS IC Electronic Volume Controller for Cars Overview The LC75421M is an electronic volume controller that enables control of volume, balance, fader, bass/treble + super bass, input switching, and input and output level control functions using only a small number of external ponents. Features - On-chip buffer amplifier cuts down number of external ponents - Low switching noise generated by on-chip switch due to use of silicon gate CMOS process - On-chip reference voltage circuit for analog ground - Controls performed with serial input (CCB) Functions - Volume: 0 dB to - 79 dB in 1-dB steps, and - ∞ (81 positions) Balance function with separate...
