The LM4911/LM4911Q is an stereo audio power amplifier capable of delivering 40mW per channel of continuous average power into a 16? load or 25mW per channel into a 32? load at 1% THD+N from a 3V power supply. \n\n 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). \n\n 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. Additionally, the LM4911/LM4911Q features an internal thermal shutdown protection mechanism. \n\n The LM4911/LM4911Q is unity gain stable and may be configured with external gain-setting resistors.\n\n A Q-grade version is available for automotive applications. It is AEC-Q100 grade 2 qualified and packaged in a 10–pin MSOP package (LM4911QMM). \n\n Key SpecificationsPSRR at 217Hz and 1kHz\n\n 65dB (typ)\n\n Output Power at 1kHz with VDD = 2.4V, \n\n 1% THD+N into a 16? load\n\n25mW (typ) \n\n Output Power at 1kHz with VDD = 3V, \n\n 1% THD+N into a 16? load\n\n40mW (typ) \n\n Shutdown Current\n\n 2.0μA (max)\n\n Output Voltage change on release from\n\n Shutdown VDD = 2.4V, RL = 16?
