LM49270 Filterless 2.2W Stereo Class D Audio Subsystem

LM49270 Description

LM49270 Filterless 2.2W Stereo Class D Audio Subsystem with OCL Headphone Amplifier, 3D Enhancement, and Headphone Sense December 2006 LM49270  Filt.
The LM49270 is a fully integrated audio subsystem designed for stereo multimedia applications.

LM49270 Features

* National’s Output Capacitor-less (OCL) architecture that eliminates the output coupling capacitors required by traditional headphone amplifiers. The IC features a headphone sense input (HPS) that automatically detects the presence of a headphone and configures the device accordingly. The LM49270 can

LM49270 Applications

* The LM49270 combines a 2.2W stereo Class D amplifier with a 155mW stereo headphone amplifier, volume control, headphone sense, and National’s unique 3D sound enhancement into a single device. The LM49270 uses flexible I2C control interface for multiple application requirements. The filterless stere
