LC75382E - Electronic Tone Control

Key Features

  • Volume: Controls the left and right volume levels independently from 0 dB to.
  • 78 dB (in 2 dB steps) and.
  • ∞ dB (41 settings). Since the left and right levels are independent this circuit also functions as a balance control.
  • Fader: Attenuates either the rear or front outputs over 16 levels, from 0 dB to.
  • 20 dB in 2 dB steps, from.
  • 20 dB to.
  • 25 dB in 5 dB step, from.
  • 25 dB to.
  • 45 dB in 10 dB steps and then to.

Ordering number : EN4881A CMOS LSI LC75382E Electronic Tone Controls for Car Stereo Systems Overview The LC75382E is an electronic tone control IC that can implement, with minimal external components, the complete range of tone and volume controls required in a car stereo, including volume, balance, fader, bass and treble, input switching and input level controls. Features • Volume: Controls the left and right volume levels independently from 0 dB to –78 dB (in 2 dB steps) and –∞ dB (41 settings). Since the left and right levels are independent this circuit also functions as a balance control.
