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.

Functions

• Volume: 81 levels: 0 dB to –79 dB (in 1 dB steps) and

–

∞.

The left and right channels are controlled independently,

allowing a balance function to be implemented.

• Bass: Peaking characteristics bass control with ±20 dB

range in 2 dB steps.

• Treble: Shelving characteristics treble control with ±10

dB range in 2 dB steps.

• Selector: One of 4 inputs can be selected for both left

and right channels.

• Input gain: Input signal amplification from 0 to +30 dB

(in 2 dB steps)

Features

• Built-in buffer amplifiers reduce the number of external

components required.

• 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.

• Built-in zero cross circuits minimize switching noise

when input signals are present.

• All functions are controlled from serial data. Supports

the CCB bus.
