Overview

The LC7535M is an electronic volume and loudness

control IC that provides volume, balance, and loudness

functions with a minimal number of external components

and that can be controlled electronically.

Functions

• Volume: Provides 81 positions from 0 dB to –79 dB in

1-dB steps and –

∞. A balance function can be

implemented by controlling the left and right volume

levels independently.

• Loudness: A loudness function can be implemented by

attaching external capacitors at the output tap provided

at the –20-dB position in the 5-dB step volume control.

• S (select) pin: Up to two LC7535M chips can be used on

the same bus.

• Serial

data

input:

The

LC7535M

supports

communication with the controller in the CCB format.

Feature

• High voltage-handling capacity: ±16 V.
