Two-Channel Electronic Volume Control

LC75366, 75366M

Overview

The LC75366 (DIP20) and the LC75366M (MFP20) are

electronic volume controls that can be controlled by serial

input data and provide volume, balance and loudness

functions.

Features

• Silicon gate CMOS process for low switching noise

Functions

• Volume: 0 dB to –68 dB (in 2 dB steps) and –

∞;

36 positions.

A balance function can be implemented by controlling

the left and right channel volume settings independently.

• Loudness: Taps are provided at the –20 dB positions in

the 10 dB step resistor ladder used by the volume

control function. A loudness function can be

implemented by attaching external RC circuits at these

tap points.

• An address selection pin (the S pin) allows two

LC75366 chips to be used on the same bus.

• Serial data input: Supports CCB* format communication

with the system controller.
