LC75421

Electronic Volume Controller for Cars

Overview\nThe 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 components.\nFunctions\n? Volume: 0 dB to –79 dB in 1-dB steps, and ; ? On-chip buffer amplifier cuts down number of external components\n? Low switching noise generated by on-chip switch due to use of silicon gate CMOS process\n? On-chip reference voltage circuit for analog ground\n? Controls performed with serial input (CCB);
