LC75410W - Electronic Volume Controller

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) Functions.
  • Volume: 0 dB to.
  • 79.5 dB in 0.5-dB step.
