音频放大器 14VP-P Class G Ceramic Speaker Driver

14VP-P,Class G Ceramic Speaker Driver

General Description

The MAX9788ETI+T 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, guaranteeing an output of 14VP-P.

The MAX9788 maximizes battery life by offering highperformance 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.

The MAX9788 is ideally suited to deliver the high output-voltage  swing required to drive ceramic/piezoelectric  speakers.
