ADS5281中文资料八通道、12 位、50MSPS 模数转换器 (ADC)数据手册TI规格书

描述 Description

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&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.
