LM49101 - Mono Class AB Audio Subsystem

LM49101 Description

LM49101Mono Class AB Audio Subsystem with a True Ground Headphone Amplifier and Earpiece Switch www.DataSheet4U.com LM49101 March 23, 2009 Mono Cl.
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 s.

LM49101 Features

* a 32
* step digital volume control on the input stage and an 8
* step digital volume control on the headphone output stage. The digital volume control and output modes, programmed through a two-wire I2C compatible interface, allows flexibility in routing and mixing audio channels. The LM

LM49101 Applications

* The high level of integration minimizes external components. The True Ground headphone amplifier eliminates the physically large DC blocking output capacitors reducing required board space and reducing cost.
*  Output Power   VDDLS = 3.3V, VDDHP = 2.75V   1% THD+N RL = 8Ω speaker RL = 32Ω headp
