GENERAL DESCRIPTION
The AD12401 is a 12-bit analog-to-digital converter (ADC) with a transformer-coupled analog input and digital postprocessing for enhanced SFDR. The product operates at up to 400 MSPS conversion rate with outstanding dynamic performance in wideband carrier systems. The AD12401 requires a 3.7 V analog supply and 3.3 V 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 AD12401 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.
PRODUCT HIGHLIGHTS
1. Guaranteed sample rate up to 400 MSPS. 2. Input signal conditioning with optimized d……
