MAX9756
Description
The MAX9756/MAX9757/MAX9758 bine dual, 2.3W, bridge tied load (BTL) stereo audio power amplifiers and a Direct Drive TM headphone amplifier in a single device. These devices feature single-supply voltage operation, shutdown mode, logic-selectable gain, a headphone sense input, a 31-step analog volume control, and industry-leading click-and-pop suppression. The headphone amplifier uses Maxim’s patent-pending Direct Drive architecture that produces a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors. The MAX9756/MAX9757 feature automatic level control (ALC) that automatically limits output power to the speaker in the event of an overpowered output. The MAX9756/MAX9758s’ 150m A internal linear regulator provides a plete solution for DAC- or CODECbased designs. The MAX9756/MAX9757/MAX9758 are offered in spacesaving, thermally efficient 32-pin (5mm x 5mm x 0.8mm) and 36-pin thin QFN (6mm x 6mm x 0.8mm) packages. All devices are...
