LC75392, 75392M

Single-Chip Electronic Volume Control System

Overview

The LC75392 (DIP-30SD) and the LC75392M (MFP-

30S) are electronic volume control ICs that provide input

and output switching, volume, and tone control functions

controlled by data transferred over a serial interface.

Functions

• Input and output switching: Four inputs and outputs can

be switched independently.

• Volume control: A balance function can be implemented

by controlling the left and right levels independently.

Each channel can be set to 0 to –20 dB in 2 dB steps,

–20 to –32 dB in 3 dB steps, –32 to –52 dB in 4 dB

steps, –52 dB to –70 dB in 4.5 dB steps, and –∞.

•Tone controls: Internal switches are provided to select

between four sets of frequency characteristics. A buffer

function can be implemented using external

components.

Features

Serial data interface: Support for control and

communication in the CCB format.
