LM4915 Datasheet Pseudo-differential Mono Headphone Amplifier

Manufacturer: Texas Instruments

Overview: LM4915 www.ti.com SNAS176A – MAY 2003 – REVISED MAY 2013 LM4915 Pseudo-Differential Mono Headphone Amplifier with Fixed 6dB Gain Check for Samples:.

General Description

The LM4915 is a pseudo-differential audio power amplifier primarily designed for demanding applications in mobile phones and other portable audio device applications with mono headphones.

It is capable of delivering 90 miliwatts of continuous average power to a 32Ω BTL load with less than 1% distortion (THD+N) from a 3VDC power supply.

Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components.
