LM4911 Datasheet Stereo 40mw Low Noise Headphone Amplifier

Manufacturer: Texas Instruments

Overview: LM4911, LM4911Q www.ti.com SNAS152M – MAY 2004 – REVISED JUNE 2011 LM4911/LM4911Q Stereo 40mW Low Noise Headphone Amplifier with Selectable Capacitive Coupled or OCL Output Check for Samples: LM4911,.

General Description

The LM4911/LM4911Q 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 LM4911/LM4911Q does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems.
