Overview
The LC75412E and 75412W are electronic volume controllers that enable control of volume, balance, fader, bass/treble, loudness, input switching, and input gain using only a small number of external components.

Features
• On-chip buffer amplifier cuts down number of external
   components
• Low switching noise generated by on-chip switch
   through use of silicon gate CMOS process, for low
   switching noise when there is no signal
• Low switching noise when there is a signal due to use
   of on-chip zero-cross switching circuit
• On-chip 1/2 VDD reference voltage circuit
• Controls performed with serial input (CCB)
