This document provides detailed information about ADR420/ADR421/ADR423/ADR425, including features, characteristics, applications and so on.
The ADR42x series (ADR420, ADR421, ADR423, ADR425) are ultra‑precision XFET voltage references offering low noise, high accuracy and long‑term stability in 8‑lead SOIC and MSOP packages. They feature a patented temperature‑drift correction technique, low hysteresis and a trim terminal for fine output adjustment.
The handbook provides detailed electrical specifications, pin configurations, absolute maximum ratings, ESD precautions and typical application guidance for precision data‑acquisition, medical instrumentation, optical network control and industrial process control systems.
