Windows Vista-Compliant Class D Speaker Amplifiers with DirectDrive Headphone Amplifiers
General Description
The MAX9791 combines a stereo 2W Class D power amplifier, a stereo 180mW DirectDrive ® headphone amplifier, and a 120mA low-dropout (LDO) linear regulator in a single device.

The MAX9792 combines a mono 3W Class D power amplifier, a stereo 180mW DirectDrive headphone amplifier, and a 120mA LDO linear regulator in a single device. The MAX9791/MAX9792 feature Maxim's patented** DirectDrive headphone amplifier architecture that produces a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, saving cost, board space, and component height. High 107dB DC PSRR and low 0.006% THD+N ensure clean, low-distortion amplification of the audio signal. The ground sense feature senses and corrects for the voltage difference between the output jack ground and device signal ground. This feature minimizes headphone amplifier cr
