The LM4809 is a dual audio power amplifier capable of delivering 105mW per channel of continuous average power into a 16Ù load with 0.1% (THD+N) from a 5V power supply. This*LM4809MBD** is an evaluation board designed to ease the evaluation and effort during the development of a circuit using the LM4809M. It is an easy to use stand-alone board that requires power and GND, an input signal and an output load.
