CMOS IC
LC75348, 75348M
Single-Chip Electronic Volume and
Tone Control System
Overview
The LC75348 and LC75348M are electronic volume and
tone control ICs that provide volume, balance, 2-band
equalizer, input gain control, and input switching
functions while requiring a minimal number of external
components.

鈥?Volume: 81 levels: 0 dB to 鈥?9 dB (in 1 dB steps) and
鈥撯垶.
The left and right channels are controlled independently,
allowing a balance function to be implemented.
鈥?Bass: Peaking characteristics bass control with 鹵20 dB
range in 2 dB steps.
鈥?Treble: Shelving characteristics treble control with 鹵10
dB range in 2 dB steps.
鈥?Selector: One of 4 inputs can be selected for both left
and right channels.
鈥?Input gain: Input signal amplification from 0 to +30 dB
(in 2 dB steps)

Features
鈥?Built-in buffer amplifiers reduce the number of external
components required.
鈥?Fabricated in a silicon gate CMOS process for minimal
switching noise from built-in switches and minimal
switching noise even when there is no input signal.
鈥?Built-in zero cross circuits minimize switching noise
when input signals are present.
鈥?Built-in V
