1 / 24 page  w WM1824 24-bit 192kHz Stereo DAC with 2Vrms Ground Referenced Line Output WOLFSON MICROELECTRONICS plc Production Data, December 2011, Rev 4.1 Copyright 2011 Wolfson Microelectronics plc DESCRIPTION The WM1824 is a stereo DAC with integral charge pump. 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 via a hardware control interface. The device supports all common audio sampling rates between 8kHz and 192kHz using all common MCLK fs rates. The audio interface operates in slave mode. The WM1824 has a 3.3V tolerant digital interface, allowing logic up to 3.3V to be connected. The device is available in a 24-pin QFN. FEATURES High performance stereo DAC with ground referenced line driver Audio Performance 106dB SNR (‘A-weighted’) -89dB THD @ -1dBFS 120dB mute attenuation All common sample rates from 8kHz to 192kHz supported Hardware control mode Data formats: LJ, I 2S Maximum 1mV DC offset on Line Outputs Pop/Click suppressed Power Up/Down Sequencer AVDD, LINEVDD and DBVDD can operate at +3.3V ±10% allowing single supply 24-lead QFN package Operating temperature range: -40°C to 85°C APPLICATIONS Consumer digital audio applications requiring 2Vrms output Games Consoles Set Top Box A/V Receivers DVD Players Digital TV BLOCK DIAGRAM |
