MAX9707 Datasheet | Maxim Integrated

Description 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. The crossover frequency is pin-selectable to four different frequencies to acmodate a variety of speaker configurations. The internal Class D amplifiers feature low-EMI, spread-spectrum outputs. No output filters are required. The MAX9706 features Maxim’s patented Direct Drive™ headphone amplifier, providing ground-referenced headphone outputs without the need for bulky DC-coupling capacitors. The headphone outputs are capable of delivering 95m W per channel into 16Ω from a 3.3V supply, and are protected against ESD up to ±8k V. The MAX9706/MAX9707 feature pin-programmable gain, synchronization inputs and...
