The AD12400 is a 12-bit analog-to-digital converter (ADC)
with a transformer-coupled analog input and digital post-
processing for enhanced SFDR. The product operates at a 400
MSPS conversion rate with outstanding dynamic performance
in wideband carrier systems.
The AD12400 requires 3.8 V analog, 3.3 V digital, and 1.5 V
digital supplies, and provides a flexible encode signal that can
be differential or single-ended. No external reference is
The AD12400 package style is an enclosed 2.9" × 2.6" × 0.6"
module. Performance is rated over a 0°C to 60°C case
