WM8948規(guī)格書(shū)詳情
DESCRIPTION
The WM8948 is a highly integrated low power hi-fi CODEC designed for portable devices such as digital still cameras.
Up to 6 analogue inputs may be connected; a 2-channel digital microphone interface is also provided. Flexible output mixing options support single-ended and differential configurations, with outputs derived from the digital audio paths or from analogue bypass paths. Twin stereo outputs or stereo line and mono BTL headphone/speaker drive may be supported.
