LM4929 - Stereo 40mW Low Noise Headphone Amplifier

General Description

The LM4929 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.

Key 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.

LM4929 Stereo 40mW Low Noise Headphone Amplifier with OCL Output December 2004 LM4929 Stereo 40mW Low Noise Headphone Amplifier with OCL Output General Description The LM4929 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 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.
