M62440FP

PRELIMINARY

Notice ; This is not a final specification.

some parametric limits are subject to change.

Description

The M62440FP is an IC developed for car audio, it has a built-in 4ch input selector,
master volume, loudness, tone control and fader volume blocks. All of these blocks are
controlled via serial data.Thank to the used zero crossing detector, very low click noise
are obtained.

Features

Built-in zero cross detector prevents click noise
