DESCRIPTION
The WM8945 is a highly integrated low power hi-fi CODEC designed for portable devices such as digital still cameras.
Up to 4 analogue inputs may be connected; a 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. Mono line output and mono BTL headphone/speaker drive is supported.
