Texas Instruments  LM4879SDBD

The LM4879 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 1.1 watt of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5VDC power supply.

This LM4879SDBD is an evaluation board designed to ease the evaluation and effort during the development of a circuit using the LM4879SD. It is an easy to use stand-alone board that requires power and GND, an input signal and an output load.
