General Description
The MAX9738 features a mono Class G power amplifi-
er with an integrated inverting boost converter. The
Class G amplifier is specifically designed to drive the
high capacitance of a ceramic/piezoelectric loud-
speaker. The inverting boost converter can typically
supply up to 400mA of peak output current, allowing
for a constant output of 16VP-P over the 2.7V to 5.5V
supply voltage range.
The MAX9738 maximizes battery life by offering high-
performance efficiency. Maxim’s proprietary output
stage provides efficiency levels greater than Class AB
devices without the EMI penalties commonly associat-
ed with Class D amplifiers.
The MAX9738 is ideally suited to deliver the high output
voltage swing required to drive ceramic/piezoelectric
speakers.
The device utilizes fully differential inputs and outputs,
comprehensive click-and-pop suppression, shutdown
control, and soft-start circuitry. The MAX9738 is fully
specified over the -40°C to +85°C extended tempera-
ture range and is available in an ultra-small, lead-free
5x4 WLP (2.5mm x 2mm) package.
