Cirrus Logic, Inc. Integrated Circuits (ICs) - Data Acquisition - ADCs-DACs - Special Purpose WM8521CH9GED

The WM8521CH9GED is a stereo digital-to-analog converter (DAC) designed for consumer digital audio applications requiring a 2Vrms output. It operates at a supply voltage of 9V and supports audio sampling rates from 8kHz to 192kHz with a 24-bit multi-bit sigma-delta architecture. The device features integrated output op-amps, which minimize external component needs, and is capable of handling digital audio input formats such as I¬=S, Right Justified, and DSP. With a signal-to-noise ratio (SNR) of 98dB and total harmonic distortion (THD) of -81dB at 48kHz, the WM8521CH9GED offers high audio performance. It is packaged in a 14-lead SOIC format and is suitable for applications including DVD players, digital TVs, digital set-top boxes, and A/V receivers. The device is controlled via a hardware interface that allows access to features like de-emphasis and mute.
