LM4910 Datasheet Output Capacitor-less Stereo 35mW Headphone Amplifier

Manufacturer: Texas Instruments

General Description

The LM4910 is an audio power amplifier primarily designed for headphone applications in portable device applications.

It is capable of delivering 35mW of continuous average power to a 32Ω load with less than 1% distortion (THD+N) from a 3.3VDC power supply.

The LM4910 utilizes a new circuit topology that eliminates output coupling capacitors and half-supply bypass capacitors.
