General Description
The MAX9750/MAX9751/MAX9755 combine a stereo,
2.6W audio power amplifier and stereo DirectDrive
110mW headphone amplifier in a single device. The
headphone amplifier uses Maxim’s DirectDrive architec-
ture that produces a ground-referenced output from a
single supply, eliminating 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.
The MAX9750 features an analog volume control, and a
BEEP input. The MAX9751 features a 2:1 input multiplexer,
allowing multiple audio sources to be selected. All devices
feature a single-supply voltage, a shutdown mode, logic-
selectable gain, and a headphone sense input. Industry-
leading click-and-pop suppression eliminates audible
transients during power and shutdown cycles.
The MAX9750/MAX9751/MAX9755 are offered in a
space-saving, thermally efficient 28-pin thin QFN (5mm
x 5mm x 0.8mm) package. These devices have thermal-
overload and output short-circuit protection, and are
specified over the extended -40°C to +85°C tempera-
ture range.
