General Description
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 indus-
try-leading click-and-pop suppression. The headphone
amplifier uses Maxim’s DirectDrive architecture that pro-
duces 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 speak-
er in the event of an overpowered output.
The MAX9756/MAX9758s’ 150mA internal linear regula-
tor provides a complete solution for DAC- or CODEC-
based designs.
The MAX9756/MAX9757/MAX9758 are offered in space-
saving, 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 specified over the extended -40°C to
+85°C temperature range.
