产品描述

ADS5547 is a high performance 14-bit, 210-MSPS A/D converter. It offers state-of-the art functionality and performance using advanced techniques to minimize board space. With high analog bandwidth and low jitter input clock buffer, the ADC supports both high SNR and high SFDR at high input frequencies. It features programmable gain options that can be used to improve SFDR performance at lower full-scale analog input ranges.

In a compact 48-pin QFN, the device offers fully differential LVDS DDR (Double Data Rate) interface while parallel CMOS outputs can also be selected. Flexible output clock position programmability is available to ease capture and trade-off setup for hold times. At lower sampling rates, the ADC can be operated at scaled down power with no loss in performance. The ADS5547 includes an internal reference, while eliminating the traditional reference pins and associated external decoupling. The device also supports an external reference mode.

The device is specified over the industrial temperature range (-40°C to 85°C).
