ADS5517 is a high performance 11-bit, 200-MSPS Flexible output clock position programmability is A/D converter. It offers state-of-the art functionality available to ease capture and trade-off setup for hold and performance using advanced techniques to times. At lower sampling rates, the ADC can be minimize board space. With high analog bandwidth operated at scaled down power with no loss in and low jitter input clock buffer, the ADC supports performance. The ADS5517 includes an internal both high SNR and high SFDR at high input reference, while eliminating the traditional reference frequencies. It features programmable gain options pins and associated external decoupling. The device that can be used to improve SFDR performance at alsosupportsanexternalreferencemode. lowerfull-scaleanaloginputranges. The device is specified over the industrial temperaturerange(-40(cid:176) Cto85(cid:176) C).
