WM8521 Datasheet | Wolfson Microelectronics plc

w Stereo DAC with Integrated Output Stage for 2Vrms LINE OUT DESCRIPTION Features The WM8521 is a 192k Hz stereo DAC with an integrated output op-amp stage, designed to generate a 2.0Vrms output signal directly, so reducing external ponent requirements in digital audio applications. WM8521 es 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 8k Hz to 192k Hz are supported. The audio interface supports I2S, Right Justified and DSP digital audio formats. - Audio Performance - DAC SNR 98d B (‘A’ weighted @ 48k Hz) - THD -81d B (‘A’ weighted @ 48k Hz) - DAC Sampling Frequency: 8k Hz - 192k Hz - Pin Selectable Audio Data Interface Format - I2S, 16-bit Right Justified or 16bit DSP - 2.0 Vrms output at 12V or 9V supply - 7.6V to 13.2V Analogue, 2.7V to 3.6 Digital Supply - 14-lead SOIC Package APPLICATIONS - Consumer digital audio applications requiring 2 Vrms output - DVD Players - Digital TV - Digital Set Top Boxes - A/V Receivers The devices are controlled via a hardware interface which provides access to Features including de-emphasis, mute and data formats. These devices are pin equivalent and are available in a 14-lead SOIC package.
