LM4929 - LM4929 Stereo 40mW Low Noise Headphone Amplifier with OCL Output - 无 - 音频子系统 - TI公司（Texas Instruments，德州仪器）
The LM4929 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.
Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. 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.
