描述 Description

The ADS5287 is a high-performance, low-power, octal channel analog-to-digital converter (ADC). Available in a 9mm × 9mm QFN package, with serialized low-voltage differential signaling (LVDS) outputs and a wide variety of programmable features, the ADS5287 is highly customizable for a wide range 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 ADS5287 is specified over the industrial temperature range of –40°C to +85°C.
