19-3782; Rev 1; 1/06 EVALUATION KIT AVAILABLE 2.3W Stereo Speaker Amplifiers and DirectDrive Headphone Amplifiers with Automatic Level Control MAX9756/MAX9757/MAX9758 General Description Features The MAX9756/MAX9757/MAX9758 combine dual, 2.3W, Automatic Level Control--Protects Speakers bridge tied load (BTL) stereo audio power amplifiers and Analog Volume Control a DirectDriveTM headphone amplifier in a single device.These devices feature single-supply voltage operation, 120mW DirectDrive Headphone Amplifiers (16) shutdown mode, logic-selectable gain, a headphone 150mA Adjustable LDO sense input, a 31-step analog volume control, and indus-try-leading click-and-pop suppression. The headphone Class AB, 2.3W, Stereo BTL Speaker Amplifiers amplifier uses Maxim s patent-pending DirectDrive archi- (3) tecture that produces a ground-referenced output from a High 95dB PSRR single supply, eliminating the need for large DC-blockingcapacitors. Low-Power Shutdown Mode The MAX9756/MAX9757 feature automatic level control Industry-Leading Click-and-Pop Suppression (ALC) that automatically limits output power to the speak- Short-Circuit and Thermal Protection er in the event of an overpowered output. Beep Input The MAX9756/MAX9758s 150mA internal linear regula-tor provides a complete solution for DAC- or CODEC-based designs. Ordering Information The MAX9756/MAX9757/MAX9758 are offered in space-saving, thermally efficient 32-pin (5mm x 5mm x 0.8mm) PART ALC LDO PIN-PACKAGE and 36-pin thin QFN (6mm x 6mm x 0.8mm) packages.All devices are specified over the extended -40°C to MAX9756ETX+ 36 Thin QFN-EP* +85°C temperature range. MAX9757ETJ+ -- 32 Thin QFN-EP* Applications MAX9758ETJ+ -- 32 Thin QFN-EP* Note: All devices specified for -40°C to +85°C operating Notebook PCs Flat-Panel TVs
