MAX9779 General Description


The MAX9779 combines 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 through the Class AB speaker amplifiers.

The MAX9779 features 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 MAX9779 is offered in a space-saving, thermally efficient 28-pin thin QFN (5mm x 5mm x 0.8mm) package.The device has thermal-overload and output short-circuit protection, and is specified over the extended -40°C to +85°C temperature range.
