LC75371M
Overview
The LC75371M is an electronic tone/volume control LSI that can implement, with minimal external ponents, volume, balance, fader, bass and treble, loudness, input switching, and input level controls.

Functions
- Volume control: From 0 to
- 79 d B in 1-d B steps plus
- ∞ for a total of 81 settings. Since the left and right levels can be set independently, this function can also be used to implement a balance function.
- Fader: Attenuates either the rear or front channels to one of 16 levels. (Provides 16 settings, namely, from 0 to
- 20 d B in 2-d B steps, from
- 20 to
- 25 d B in one 5-d B step, from
- 25 to
- 45 d B in 10-d B steps,
- 60 d B, and
- ∞.)
- Bass and treble controls: Forms an NF-type tone control circuit (LUX type) using external capacitors. Provides 15 settings each for the bass and treble controls.
- Loudness control: A loudness function can be implemented by attaching external RC circuits at the taps provided from the volume...
