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 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
ADS5287 is specified over the industrial temperature
range of –40°C to +85°C.
