LM4912
Overview
The LM4912 is an stereo audio power amplifier capable of delivering 40mW per channel of continuous average power into a 16Ω load or 25mW per channel into a 32Ω load at 1% THD form a 3V power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components.
