The ADS528x is a family of high-performance, low-power, octal channel analog-to-digital converters (ADCs). Available in either a 9mm × 9mm QFN package or an HTQFP-80 package, with serialized low-voltage differential signaling (LVDS) outputs and a wide variety of programmable features, the ADS528x is highly customizable for a diversity of applications and offers an unprecedented level of system integration. An application note, XAPP774 (available at www.xilinx.com), describes how to interface the serial LVDS outputs of TI's ADCs to Xilinx® field-programmable gate arrays (FPGAs). The ADS528x family is specified over the industrial temperature range of -40°C to +85°C.
