The MAX9756/MAX9757/MAX9758 combine dual, 2.3W, bridge tied load (BTL) stereo audio power amplifiers and a DirectDriveTM 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 DirectDrive architecture that produces a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors. |
