LM49250 - Enhanced Emissions Suppression Stereo Class D Audio Sub-System

The LM49250 is a fully integrated audio subsystem designed for stereo cell phone applications.

The LM49250 combines a 2.4W/Ch stereo class D speaker amplifiers with a 45mW/Ch stereo ground referenced headphone amplifier, a class AB earpiece amplifier, National 3D enhancement, volume control, and an

LM49250 Features

* a new circuit technology that utilizes a charge pump to generate a negative supply voltage. This allows the headphone outputs to be biased about ground, thereby eliminating the output-coupling capacitors. For improved noise immunity, the LM49250 features fully differential left, right and mono input
