Manufacturer: Texas Instruments

Overview: LM49101, LM49101TMEVAL www.ti.com SNAS475A – MARCH 2009 – REVISED APRIL 2013 LM49101 Mono Class AB Audio Subsystem with a True Ground Headphone Amplifier and Earpiece Switch Check for Samples: LM49101,.

General Description

The LM49101 is a fully integrated audio subsystem with a mono power amplifier capable of delivering 540mW of continuous average power into an 8Ω BTL speaker load with 1% THD+N using a 3.3V supply.

The LM49101 includes a separate stereo headphone amplifier that can deliver 44mW per channel into 32Ω loads using a 2.75V supply.

The LM49101 has four input channels.

Key Features
