The LM4911/LM4911Q is an stereo audio power amplifier capable of delivering 40mW per channel of continuous average power intoa 16? load or 25mW per channel into a 32? 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 externalcomponents. Since the LM4911/LM4911Q does not require bootstrap capacitors or snubber networks, it is optimally suited forlow-power portable systems. Inaddition, the LM4911/LM4911Q may be configured for either single-ended capacitively coupledoutputs 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 timewith less than 1mV voltage change at outputs on release. Additionally, the LM4911/LM4911Q features an internal thermal shutdownprotection mechanism. The LM4911/LM4911Q is unity gain stable and may be configured with external gain-setting resistors. A Q-grade version is available for automotive applications. It is AEC-Q100 grade 2 qualified and packaged in a 10–pin MSOPpackage (LM4911QMM).
