MAX9722 chip amplification
The device uses an audio amplifier chip stereo DirectDrive 130mW @ 32Ω MAX9722 to his headphones.
The chip meets the specifications for a clean, consistent sound reproduction in the context of a nomadic / compact sound system.
There are differential inputs and suppression of enhanced noise. The apparatus thus sees low distortion (THD + N of 0.03%), a 91dB signal to noise ratio inherent protection anti clicks / pops and a low audible spectrum very well preserved through integrated on each output capacitors,
