DESCRIPTION  
•
High Dynamic Performance:  
The ADS424x/422x are low-speed variants of the  
ADS42xx ultralow-power family of dual-channel,  
14-bit/12-bit analog-to-digital converters (ADCs).  
Innovative design techniques are used to achieve  
–
–
88dBc SFDR at 170MHz  
71.4dBFS SNR at 170MHz  
•
•
Crosstalk: > 90dB at 185MHz  
Programmable Gain up to 6dB for  
SNR/SFDR Trade-off  
DC Offset Correction  
Output Interface Options:  
high-dynamic  
performance,  
while  
consuming  
extremely low power with 1.8V supply. This topology  
makes the ADS424x/422x well-suited for multi-carrier,  
wide-bandwidth communications applications.  
•
•
The ADS424x/422x have gain options that can be  
used to improve SFDR performance at lower  
full-scale input ranges. These devices include a dc  
offset correction loop that can be used to cancel the  
ADC offset. Both DDR (double data rate) LVDS and  
parallel CMOS digital output interfaces are available  
in a compact QFN-64 PowerPAD™ package.  
–
–
1.8V parallel CMOS interface  
Double data rate (DDR) LVDS with  
programmable swing:  
–
–
Standard swing: 350mV  
Low swing: 200mV  
•
•
Supports Low Input Clock Amplitude  
Down to 200mVPP  
Package: QFN-64 (9mm × 9mm)  
The devices include internal references while the  
traditional reference pins and associated decoupling  
capacitors have been eliminated. All devices are  
specified over the industrial temperature range  
(–40°C to +85°C).
