LC75397E

Single Chip Electronic Volume and Tone Control System

Overview

The LC75397 is an electronic volume control system

providing control over volume, balance, 4-band equalizer,

bass, and input switching based on serial inputs.

Functions

• Volume control:

The chip provides 81 levels of volume attenuation: in 1-

dB step between 0 dB and –79 dB and –∞.

This circuit can control a total of 5 independent

channels.

• Equalizer:

The chip provides control in 2-dB steps over the range

between +10 dB and –10 dB. Three of the four bands

have peaking equalization; the remaining one, shelving

equalization.

• Selector:

The left and right channels each offer a choice of six

inputs. The L6 and R6 inputs can be turned on and off

independently. An external constant determines the

amplification for the input signal.

• Input gain:

The input signal can be amplified by 0 to +30 dB in 2-

dB steps.

• Bass control:

The bass can be controlled over a ±10 dB range in 2-dB

steps.

Features

• Built-in buffer amplifiers reduce the number of external

parts required.

• Silicon gate CMOS process reduces the noise of built-in

switch.

• Built-in analog ground reference voltage generator

circuit

• All functions are controlled by serial input data. This IC

supports the CCB standard.
