ADS5281

12位八通道ADC系列高达65MSPS 12-Bit Octal-Channel ADC Family Up to 65MSPS

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 &3146;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.
