IS31AP4915A - CHARGE PUMP CERAMIC SPEAKER DRIVER

General Description

The IS31AP4915A

Key Features

  • a mono power amplifier with an integrated charge-pump power supply specifically designed to drive the high capacitance of a ceramic loudspeaker. The IS31AP4915A maximizes battery life by offering high performance efficiency. The IS31AP4915A is ideally suited to deliver the high output-voltage swing required to drive ceramic/piezoelectric speakers. The device utilizes comprehensive click-and-pop suppression and shutdown control. The IS31AP4915A is fully specified over the -40°C to +85°C extended.
