DESCRIPTION
The LM4911/LM4911Q 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+N from a 3V power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components.
