MAX9707 Overview
The MAX9706/MAX9707 bine three high-efficiency Class D amplifiers with an active crossover to provide stereo highpass outputs, and a mono lowpass output. All three channels deliver up to 2.3W at 1% THD+N per channel into 4Ω when operating from a 5V supply. An internal active filter processes the stereo inputs (left and right) into stereo highpass and mono lowpass outputs.
