MAX978

General Description

Features

The MAX9788 features a mono Class G power amplifier

with an integrated inverting charge-pump power supply

specifically designed to drive the high capacitance of a

ceramic loudspeaker. The charge pump can supply

greater than 700mA of peak output current at 5.5VDC,

o Integrated Charge-Pump Power Supply—No

Inductor Required

o 14V

Voltage Swing into Piezoelectric Speaker

P-P

o 2.7V to 5.5V Single-Supply Operation

o Clickless/Popless Operation

guaranteeing an output of 14V

P-P

The MAX9788 maximizes battery life by offering high-

performance efficiency. Maxim’s proprietary Class G

output stage provides efficiency levels greater than

Class AB devices without the EMI penalties commonly

associated with Class D amplifiers.

o Small Thermally Efficient Packages

4mm x 4mm 28-Pin TQFN

2mm x 2.5mm 20-Bump UCSP

The MAX9788 is ideally suited to deliver the high out-

put-voltage swing required to drive ceramic/piezoelec-

tric speakers.
