The LM4808M is a dual-channel audio amplifier rated for 0.15 W per channel, designed for low-power audio output in portable or line-level applications. The two channels support stereo operation, making it a fit for headphone drivers, small speakers, or audio pre-amplifier stages in consumer electronics, instrumentation, and communication equipment.
0.15 W per channel — what it means for the BOM
At 0.15 W per channel, this part occupies the low-power end of the audio amplifier spectrum. It is sized for driving small speakers or headphones where output volume is secondary to board space and supply draw. If the load demands more than 0.15 W continuous, a higher-power class-AB or class-D amplifier is needed; below that threshold, the LM4808M keeps the BOM simple and the thermal footprint small.
