Windows Vista-Compliant Class D Speaker Amplifiers With DirectDrive Headphone Amplifiers

The MAX9791 combines a stereo 2W Class D power Amplifier a stereo 180mW DirectDrive Headphone Amplifier and a 120mA low-dropout (LDO) linear regu- lator 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 Maxims patented** DirectDrive Headphone Amplifier architecture that pro- duces 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. By Maxim Integrated Products
