Product Summary

The WM9713LGEFL is an AC’97 Audio + Touchpanel CODEC designed for mobile computing and communications. The WM9713LGEFL is architected for dual CODEC operation, supporting Hi-Fi stereo Codec functions via the AC link interface, and additionally supporting voice Codec functions via a PCM type Synchronous Serial Port (SSP). A third Aux DAC is provided which may be used to support generation of supervisory tones, or ring-tones etc. at different sample rates to the main codec. The applications of the include Personal Digital Assistants (PDA) with or without phone, Smartphones, Handheld and Tablet Computers.
