WM8521
Stereo DAC with Integrated Output Stage for 2Vrms LINE OUT
DESCRIPTION
FEATURES
The WM8521 is a 192kHz stereo DAC with an integrated output op-amp stage, designed to generate a 2.0Vrms output signal directly, so reducing external component requirements in digital audio applications.
WM8521 comes into two variants WM8521HC and WM8521H9 which offers different line drive output capabilities. WM8521HC outputs 2Vrms at 12V supply, while WM8521H9 outputs 2.0Vrms at 9V supply. WM8521HC/H9 are designed for cost sensitive consumer digital audio applications requiring 2Vrms line output.
A 24-bit multi-bit sigma delta DAC is used with oversampling digital interpolation filters. Digital audio input word lengths from 16-32 bits and sampling rates from 8kHz to 192kHz are supported.
The audio interface supports I2S, Right Justified and DSP digital audio formats.
Audio Performance - DAC SNR 98dB (‘A’ weighted @ 48kHz) - THD -81dB (‘A’ weighted @ 48kHz)
DAC Sampling Frequency: 8kHz – 192kHz Pin Selectable Audio Data Interface Format
