WM8523 w 24-bit 192kHz Stereo DAC with 2Vrms Ground Referenced Line Output DESCRIPTION FEATURES High performance stereo DAC with ground referenced line The WM8523 is a stereo DAC with integral charge pump driver and software control interface. This provides 2Vrms line Audio Performance driver outputs using a single 3.3V power supply rail. 106dB SNR (A-weighted) -89dB THD -1dBFS The device features ground-referenced outputs and the use Digital Volume control ranging from -100dB to +12dB of a DC servo to eliminate the need for line driving coupling 120dB mute attenuation capacitors and effectively eliminate power on pops and All common sample rates from 8kHz to 192kHz supported clicks. 2 I C/SPI compatible and hardware control modes 2 Data formats: LJ, RJ, I S, DSP The device is controlled and configured either via the De-emphasis supported I2C/SPI compliant serial control interface or a hardware Maximum 1mV DC offset on Line Outputs control interface. Pop/Click suppressed Power Up/Down Sequencer The device supports all common audio sampling rates AVDD and LINEVDD +3.3V 10% allowing single supply between 8kHz and 192kHz using all common MCLK fs 20-lead TSSOP package rates. Master and Slave modes are available and de- Operating temperature range: -40C to 85C emphasis is also supported. APPLICATIONS The WM8523 has a 3.3V tolerant digital interface, allowing logic up to 3.3V to be connected. Consumer digital audio applications requiring 2Vrms output Set Top Box The device is available in a 20-lead TSSOP package.
