Description

The LM48580 is a fully differential, high voltage driver for piezo actuators and ceramic speakers for portable multi-media devices. Part of TI’s Powerwise™ product line, the LM48580 Class H architecture offers significant power savings compared to traditional Class AB amplifiers. The device provides 30 VP-P output drive while consuming just 15 mW of quiescent power.

The LM48580 is a single supply driver with an integrated boost converter which allows the device to deliver 30 VP-P from a single 3.6 V supply.

The LM48580 has three pin-programmable gain settings and a low power Shutdown mode that reduces quiescent current consumption to 0.1 µA. The LM48580 is available in an ultra-small 12-bump DSBGA package.
