AD825 is a high speed, low distortion, high output drive capability JFET amplifier.
The AD825 is a low‑cost, high‑speed JFET operational amplifier optimized for signal‑conditioning and data‑acquisition applications. It offers ultra‑low input bias current, low noise, and rail‑to‑rail input capability, making it suitable as a buffer for multiplexed outputs.
The datasheet includes detailed specifications such as bandwidth, slew rate, and power‑supply requirements, as well as typical performance graphs, pin‑out diagrams, ESD protection guidelines, and an ordering guide for the 8‑lead and 16‑lead SOIC packages.
