DESCRIPTION
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).
