General Description
The MAX9779 combines a stereo, 2.6W audio power
amplifier and stereo DirectDrive 110mW headphone
amplifier in a single device. The headphone amplifier
uses Maxim’s DirectDrive architecture that produces a
ground-referenced output from a single supply, eliminat-
ing the need for large DC-blocking capacitors, saving
cost, space, and component height. A high 90dB PSRR
and low 0.01% THD+N ensures clean, low-distortion
amplification of the audio signal through the Class AB
speaker amplifiers.
The MAX9779 features a single-supply voltage, a shut-
down mode, logic-selectable gain, and a headphone
sense input. Industry-leading click-and-pop suppres-
sion eliminates audible transients during power and
shutdown cycles.
The MAX9779 is offered in a space-saving, thermally effi-
cient 28-pin thin QFN (5mm x 5mm x 0.8mm) package.
The device has thermal-overload and output short-circuit
protection, and is specified over the extended -40°C to
+85°C temperature range.
