Overview

The LC7536M is an electronic volume control that implements volume, balance, and loudness functions with a minimum number of external components, and can be controlled electronically with serial data.

Features

• High voltage handling capability: ±16 V.

Functions

• Volume: 81 positions from 0 to –79 dB (in 1-dB steps) and –∞. Since the left and right channels can be controlled separately, a balance function can be implemented easily.

• Loudness: A tap is output from the –20 dB position of a 5 dB step volume control resistor ladder. A loudness function can be implemented by connecting an external RC circuit.

• S (select): Up to two LC7536M ICs can be used on the same bus.

• Serial data input: The LC7536M supports control and communication in the CCB format.
