LM4929
Description
The LM4929 is an stereo audio power amplifier capable of delivering 40m W per channel of continuous average power into a 16Ω load or 25m W 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 ponents. Since the LM4929 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. The LM4929 is configured for OCL (Output Capacitor-Less) outputs, operating with no DC blocking capacitors on the outputs. The LM4929 features a low-power consumption shutdown mode with a faster turn on time. Additionally, the LM4929 features an internal thermal shutdown protection mechanism. The LM4929 is unity gain stable and may be configured with external gain-setting resistors.
