1 / 51 page  w WM8523 24-bit 192kHz Stereo DAC with 2Vrms Ground Referenced Line Output WOLFSON MICROELECTRONICS plc To receive regular email updates, sign up at http://www.wolfsonmicro.com/enews Production Data, August 2011, Rev 4.1 Copyright ©2011 Wolfson Microelectronics plc DESCRIPTION The WM8523 is a stereo DAC with integral charge pump and software control interface. This provides 2Vrms line driver outputs using a single 3.3V power supply rail. The device features ground-referenced outputs and the use of a DC servo to eliminate the need for line driving coupling capacitors and effectively eliminate power on pops and clicks. The device is controlled and configured either via the I2C/SPI compliant serial control interface or a hardware control interface. The device supports all common audio sampling rates between 8kHz and 192kHz using all common MCLK fs rates. Master and Slave modes are available and de- emphasis is also supported. The WM8523 has a 3.3V tolerant digital interface, allowing logic up to 3.3V to be connected. The device is available in a 20-lead TSSOP or 24-lead QFN. FEATURES • High performance stereo DAC with ground referenced line driver • Audio Performance − 106dB SNR (‘A-weighted’) − -89dB THD @ -1dBFS • Digital Volume control ranging from -100dB to +12dB • 120dB mute attenuation • All common sample rates from 8kHz to 192kHz supported • I2C/SPI compatible and hardware control modes • Data formats: LJ, RJ, I2S, DSP • De-emphasis supported • Maximum 1mV DC offset on Line Outputs • Pop/Click suppressed Power Up/Down Sequencer • AVDD and LINEVDD +3.3V ±10% allowing single supply • 20-lead TSSOP or 24-lead QFN packages • Operating temperature range: -40°C to 85°C APPLICATIONS • Consumer digital audio applications requiring 2Vrms output − Set Top Box − Digital TV − DVD Players − Games Consoles − A/V Receivers |
