LM4961, Ceramic Speaker Driver

The LM4961 is an audio power amplifier primarily designed for driving Ceramic Speaker for applications in Cell Phone and PDAs.

It integrates a boost converter, with variable output voltage, with an audio power amplifier.

It is capable of driving 15Vp-p in BTL mode to 2uF+ 30 ohms load, continuous av

LM4961 Features

* a low-power consumption shutdown mode. Additionally, the LM4961 features an internal thermal shutdown protection mechanism. The LM4961 contains advanced pop & click circuitry that eliminates noises which would otherwise occur during turn-on and turn-off transitions. The LM4961 is unity-gain stable a
