The LM48560 device is a high voltage, high efficiency, Class H driver for ceramic speakers and piezo actuators. The LM48560 device’s Class H architecture offers significant power savings compared to traditional Class AB amplifiers. The device provides 30 VP–P output drive while consuming just 4 mA of quiescent current from a 3.6 V supply.

The LM48560 device features TI’s unique automatic level control (ALC) that provides output limiter functionality. The LM48560 device features two fully differential inputs with separate gain settings, and a selectable control interface. In software control mode, the gain control and device modes are configured through the I2C interface. In hardware control mode, the gain and input mux are configured through a pair of logic inputs.

The LM48560 device has a low power shutdown mode that reduces quiescent current consumption to 0.1 µA. The LM48560 device is available in an ultra-small 16-bump DSBGA package (1.97 mm × 1.97 mm).
