LM48560TLEVAL

Evaluation Board For High Voltage Class H Ceramic Speaker Driver

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

The LM48560TLEVAL demonstrates "s unique automatic level control ALC that provides output limiter functionality. The LM48560TLEVAL 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.
