The AD862x is a precision JFET input amplifier. It features true single-supply operation, low power consumption, and rail-to-rail output. Applications for the AD862x include photodiode transimpedance amplification, ATE reference level drivers, battery management, etc.
The AD862x family are precision low‑power single‑supply JFET input amplifiers with rail‑to‑rail output. They operate from 5 V to 26 V (single‑supply) or ±2.5 V to ±13 V (dual‑supply) and consume less than 630 pA per amp. Features include very low input bias current, low offset voltage, high CMRR, and stable unity‑gain operation.
The document lists detailed electrical characteristics, absolute maximum ratings, typical performance curves, application examples such as photodiode transimpedance amplifiers and automotive sensors, pin‑out tables for multiple package styles, and an ordering guide with part numbers for SC70, SOIC, MSOP and TSSOP packages.
