200mW Total Power at 160MSPS  
265mW Total Power at 250MSPS  
DESCRIPTION  
•
High Dynamic Performance:  
The ADS414x/2x are  
a family of 14-bit/12-bit  
–
–
SNR: 70.6dBFS at 170MHz  
SFDR: 84dBc at 170MHz  
analog-to-digital converters (ADCs) with sampling  
rates up to 250MSPS. These devices use innovative  
design techniques to achieve high dynamic  
performance, while consuming extremely low power  
at 1.8V supply. The devices are well-suited for  
multi-carrier,  
applications.

Output Interface  
–
Double Data Rate (DDR) LVDS with  
Programmable Swing and Strength  
wide  
bandwidth  
communications  
–
–
–
–
Standard Swing: 350mV  
The ADS414x/2x have fine gain options that can be  
used to improve SFDR performance at lower  
full-scale input ranges, especially at high input  
frequencies. They include a dc offset correction loop  
that can be used to cancel the ADC offset. At lower  
sampling rates, the ADC automatically operates at  
scaled down power with no loss in performance.  
Low Swing: 200mV  
Default Strength: 100Ω Termination  
2x Strength: 50Ω Termination  
–
1.8V Parallel CMOS Interface Also  
Supported  
•
Programmable Gain up to 6dB for SNR/SFDR  
Trade-Off  
The ADS414x/2x are available in a compact QFN-48  
pacakge and are specified over the industrial  
temperature range (–40°C to +85°C).
