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. Since the LM4911/LM4911Q does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. In addition, the LM4911/LM4911Q may be configured for either single-ended capacitively coupled outputs or for OCL outputs (patent pending).
The LM4911/LM4911Q features a low-power consumption shutdown mode and a power mute mode that allows for faster turn on time with less than 1mV voltage change at outputs on release
