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
Recommended Operating Conditions
Supply voltage range: V_CC = 6 to 9 V
V_DD = 4 to 6 V
Rated supply voltage: V_CC = 8 V
V_DD = 5 V
