CP2114-EK 4. DAC Configuration Application (AN721SW) The DAC Configuration utility is an application within the AN721 software (AN721SW) package that allows audio configuration strings to be sent to the CP2114 one-time programmable memory or RAM. The audio string is used by the CP2114 to configure the DAC/CODEC.
