19-3006; Rev 8; 6/08 EVALUATION KIT AVAILABLE 2.6W Stereo Audio Power Amplifiers and DirectDrive Headphone Amplifiers MAX9750/MAX9751/MAX9755 General Description Features The MAX9750/MAX9751/MAX9755 combine a stereo, No DC-Blocking Capacitors Required--Provides 2.6W audio power amplifier and stereo DirectDrive® Industry s Most Compact Notebook Audio 110mW headphone amplifier in a single device. The Solution headphone amplifier uses Maxim s patented DirectDrivearchitecture that produces a ground-referenced output PC2001 Compliant from a single supply, eliminating the need for large DC- 5V Single-Supply Operation blocking capacitors, saving cost, space, and componentheight. A high 90dB PSRR and low 0.01% THD+N Class AB 2.6W Stereo BTL Speaker Amplifiers ensures clean, low-distortion amplification of the 110mW DirectDrive Headphone Amplifiers audio signal. The MAX9750 features an analog volume control, and a High 90dB PSRR BEEP input. The MAX9751 features a 2:1 input multiplexer, Low-Power Shutdown Mode allowing multiple audio sources to be selected. All devicesfeature a single-supply voltage, a shutdown mode, logic- Industry-Leading Click-and-Pop Suppression selectable gain, and a headphone sense input. Industry- Low 0.01% THD+N at 1kHz leading click-and-pop suppression eliminates audibletransients during power and shutdown cycles. Short-Circuit and Thermal Protection The MAX9750/MAX9751/MAX9755 are offered in a Selectable Gain Settings space-saving, thermally efficient 28-pin thin QFN (5mm Analog Volume Control (MAX9750) x 5mm x 0.8mm) package. These devices have thermal-overload and output short-circuit protection, and are BEEP Input with Glitch Filter (MAX9750) specified over the extended -40°C to +85°C tempera- 2:1 Stereo Input MUX (MAX9751) ture range. ±8kV ESD-Protected Headphone Driver Outputs Applications Available in Space-Saving, Thermally Efficient Notebook PCs Flat-Panel TVs 28-Pin Thin QFN (5mm x 5mm x 0.8mm) Package Tablet PCs PC Displays Portable DVD Players LCD Projectors Simplified Block Diagrams Ordering Information PIN-
