6ch Electronic Volume with Tone Control
REJ03F0212-0201 Rev.2.01 Mar 31, 2008
Description
The M62446AFP is 6ch electronic volume with tone control. This IC is revised from M62446FP. The extended function of M62446AFP is volume level and tone control level. M62446AFP is easy to use more than M62446FP.
Features
* 6ch Electric volume Volume level: 0 to -95 dB (1 dB/step)* * Tone control Bass/Treble: -14 dB to +14 dB (2 dB/step)* * Noise voltage: 1.5 Vrms * 4 Output ports * Bypass mode is high quality sound. Note: * is an extended function.
Application
DVD, Home Audio equipment, TV
Recommended Operating Conditions
Supply voltage range: 4.5 to 7.5 V (analog), 4.5 V to 5.5 V (digital) Recommended supply voltage: 7.0 V (analog), 5.0 V (digital)
