General Description
The MAX9752/MAX9753/MAX9754 combine a high-effi-
ciency, 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 DirectDrive
architecture to produce a ground-referenced output
from a single supply.
The MAX9754 features a Class D stereo speaker ampli-
fier and headphone driver. The MAX9752 adds an ana-
log 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 speci-
fied 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.
