LM48821 Datasheet 52mw Differential Input Stereo Headphone Amplifier

Manufacturer: Texas Instruments

Overview: LM48821, LM48821TLEVAL www.ti.com SNAS354A – JUNE 2007 – REVISED MAY 2013 LM48821 Direct Coupled, Ultra Low Noise, 52mW Differential Input Stereo Headphone Amplifier with I2C Volume Control Check for Samples: LM48821,.

General Description

With its directly-coupled output technology, the LM48821 is a variable gain audio power amplifier capable of delivering 52mWRMS per channel into a 16Ω single-ended load with less than 1% THD+N from a 3V power supply.

The I2C volume control has a range of –76dB to 18dB.

The LM48821's Tru-GND technology utilizes advanced charge pump technology to generate the LM48821’s negative supply voltage.
