M62440FP
ELECTRIC VOLUME CONTROL WITH TONE CONTROLLER FOR 4-SPEAKER APPLICATIONS
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 4-input Selector Loudness Tone Control Bass/Mid/Treble Master Volume/Fader Volume Serial Data Control
