ADS5545 具有 LVDS/CMOS 输出的14 位 170MSPS ADC

ADS5545 is a high performance 14-bit, 170-MSPS A/D converter. It offers state-of-the-art functionality and performance using advanced techniques to minimize board space. Using an internal sample and hold and low jitter 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.
