Description

The MAX9750/MAX9751/MAX9755 combine a stereo,2.6W audio power amplifier and stereo DirectDrive 110mW headphone amplifier in a single device. The headphone amplifier uses Maxim's patented DirectDrive architecture that produces a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, saving cost, space, and component height. A high 90dB PSRR and low 0.01% THD+N ensures clean, low-distortion amplification of the audio signal.The MAX9750 features an analog volume control, and a BEEP input. The MAX9751 features a 2:1 input multiplexer,allowing multiple audio sources to be selected. All devices feature a single-supply voltage, a shutdown mode, logic-selectable gain, and a headphone sense input. Industry-leading click-and-pop suppression eliminates audible transients during power and shutdown cycles.The MAX9750/MAX9751/MAX9755 are offered in space-saving, thermally efficient 28-pin thin QFN (5mm x 5mm x 0.8mm) and 28-pin TSSOP-EP packages. MAX9750 have thermal-overload and output short-circuit protec-tion, and are specified over the extended -40°C to +85°C temperature range.
