AD626 is a low cost, true single-supply differential amplifier designed for amplifying and low-pass filtering small differential signals.
The AD626 is a true single‑supply differential amplifier designed for amplifying low‑level differential signals with a large common‑mode voltage. It provides pin‑selectable gains of 10 or 100, low input offset voltage, and optional low‑pass filtering, making it suitable for current‑sensing, bridge, and pressure‑transducer applications.
The datasheet lists detailed electrical specifications, absolute maximum ratings, ordering information, and typical performance graphs such as gain‑vs‑frequency, common‑mode rejection, and quiescent current. Package options include an 8‑lead plastic DIP and an 8‑lead SOIC, both compliant with JEDEC standards.
