FEATURES  
DESCRIPTION  
The ADS412x/4x are lower sampling speed variants  
23  
•
Ultralow Power with 1.8V Single Supply:  
of the ADS41xx family of analog-to-digital converters  
(ADCs). 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, wide  
bandwidth communications applications.  
–
–
103mW Total Power at 65MSPS  
153mW Total Power at 125MSPS  
•
High Dynamic Performance:  
–
–
SNR: 72.2dBFS at 170MHz  
SFDR: 81dBc at 170MHz  
The ADS412x/4x 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.  
•
•
Dynamic Power Scaling with Sample Rate  
Output Interface:  
–
Double Data Rate (DDR) LVDS with  
Programmable Swing and Strength  
–
–
–
–
Standard Swing: 350mV  
Low Swing: 200mV  
The ADS412x/4x are available in a compact QFN-48  
pacakge and are specified over the industrial  
temperature range (–40°C to +85°C).  
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  
•
•
DC Offset Correction  
Supports Low Input Clock Amplitude Down To  
200mVPP  
•
Package: QFN-48 (7mm × 7mm)
