WM8958ECS/R

Product Summary

The WM8958ECS/R is a highly integrated ultra-low power hi-fi CODEC designed for smart phones and other portable devices rich in multimedia features. An integrated stereo class D/AB speaker driver and class W headphone driver minimize power consumption during audio playback. The WM8958ECS/R requires only two voltage supplies, with all other internal supply rails generated from integrated LDOs. The applications of the WM8958ECS/R include Smart phones and music phones, Portable navigation, Tablets, eBooks, PMP.
