LM48410 Low-EMI, Filterless, 2.3W Stereo Class D Audio Power Amplifier with National 3D Enhancement
General Description
The LM48410 is a single supply, high efficiency, 2.3W/channel, filterless switching audio amplifier.

A low noise PWM architecture eliminates the output filter, reducing external component count, board area consumption, system cost, and simplifying design. A selectable spread spectrum modulation scheme suppresses RF emissions, further reducing the need for output filters. The LM48410 is designed to meet the demands of mobile phones and other portable communication devices. Operating from a single 5V supply, the device is capable of delivering 2.3W/channel of continuous output power to a 4 load with less than 10% THD+N. Flexible power supply requirements allow operation from 2.4V to 5.5V. The LM48410 offers two logic selectable modulation schemes, fixed fr
