LM49270 Filterless 2.2W Stereo Class D Audio Subsystem with OCL Headphone Amplifier, 3D Enhancement, and Headphone Sense
General Description
The LM49270 is a fully integrated audio subsystem designed for stereo multimedia 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 stereo class D amplifiers delivers 2.2W/channel into a 4 load with less than 10% THD+N with a 5V supply. The headphone amplifier 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
