LC75384NW Electronic Volume and Tone Controller

Ordering number : ENN6169 CMOS IC LC75384NE-R, 75384NW Electronic Volume and Tone Control for Car Stereo Systems Overview The LC75384NE-R and LC75384NW are electronic volume and tone control ICs that can implement volume, balance, fader, bass/treble/mid, loudness, input switching, and input gain control functions with a minimum number of external componen.

Features

• Volume: 81 positions: from 0 dB to
  –79 dB in 1-dB steps and
  –∞. A balance function can be implemented by controlling the left and right volume settings independently.
• Fader: Either the rear or front outputs can be attenuated over 16 positions. (16 positions: From 0 dB to
  –2 dB in 1-dB steps, from
  –2 dB to
  –20 dB in 2-dB steps, from
  –20 to
  –30 dB in one 10-dB step,
  –45 dB,
  –60 dB, and
  –∞.)
• Bass/treble/mid: Control over ±12 dB in 2-dB steps in each band.
• Input gain: The input signal can be amplified by from 0 dB to +18.75 dB in 1.25-dB steps.
• Input switching: The left and right channe.
