LM48555 - Ceramic Speaker Driver

Description

The LM48555 is an audio power amplifier designed to drive ceramic speakers in applications such as cell phones, smart phones, PDAs and other portable devices.

The LM48555 produces 15.7VP-P with less than 1% THD+N while operating from a 3.2V power supply.

Features

  • a low power shutdown mode, and differential inputs for improved noise rejection. The LM48555 includes advanced click and pop suppression that eliminates audible turn-on and turn-off transients. Additionally, the integrated boost regulator features a soft start function that minimizes transient current during power-up Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal number of external components. The LM48555 does not require bootstrap ca.
