Description

The MAX9752/MAX9753/MAX9754 combine a high-efficiency, filterless, stereo Class D audio power amplifier with a DirectDrive® headphone amplifier in a single device. The Class D amplifier operates from a single 4.5V to 5.5V supply and provides 2.2W per channel into a 4Ω load. The headphone amplifier operates from a single 3V to 5.5V supply, and uses Maxim's patented† DirectDrive architecture to produce a ground-referenced output from a single supply. The MAX9754 features a Class D stereo speaker amplifier and headphone driver. The MAX9752 adds an analog volume control and a BEEP input. The MAX9753 adds a stereo 2:1 input multiplexer. All devices feature logic-selectable gain, and a headphone sense input that detects the presence of a headphone. The MAX9752/MAX9753/MAX9754 come in 28-pin thin QFN (5mm x 5mm x 0.8mm) packages, and are specified over the extended -40°C to +85°C temperature range. For a pin-for-pin-compatible Class AB version of these devices, refer to the MAX9750/MAX9751/MAX9755 data sheet.
