This document is about AD12401, AD12401 is a 12-bit, 400 MSPS A/D converter.
The AD12401 is a 12‑bit analog‑to‑digital converter designed for high‑speed, wideband carrier systems. It features a transformer‑coupled analog input, flexible ENCODE output (single‑ended or differential), and operates up to 400 MSPS conversion rate with excellent dynamic performance.
Typical applications include communications test equipment, radar and satellite subsystems, phased‑array antennas, and secure broadband communications. The device is supplied in a 2.9" × 2.6" × 0.6" module that operates from 0 °C to 60 °C case temperature.
