GENERAL DESCRIPTION
The AD12400 is a 12-bit analog-to-digital converter 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 required. 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 temperature range.
