WM8974CGEFL Integrated Circuit Chip Mono CODEC With Speaker Driver QFN24 Audio CODEC

WM8974CGEFL Integrated Circuit Chip Mono CODEC With Speaker Driver QFN24 Audio CODEC

Product Description Of WM8974CGEFL

WM8974CGEFL is a low power, high quality mono CODEC designed for portable applications such as Digital Still Camera or Digital Voice Recorder. WM8974CGEFL operates at supply voltages from 2.5 to 3.6V, although the digital supplies can operate at voltages down to 1.71V to save power. The speaker and mono outputs use a separate supply of up to 5V which enables increased output power if required.
