The document describes the features and characteristics of the product AD626 from Analog Devices, including selectable gains, single supply operation, wide output voltage range, and optional low-pass filtering.
The AD626 differential amplifier is designed for amplifying low‑level differential signals while tolerating large common‑mode voltages. It supports single‑supply operation from +2.4 V to +10 V or dual‑supply operation from +1.2 V to +6 V, with selectable gains of 10 or 100 and optional low‑pass filtering.
Typical applications include current sensing, pressure transducer interfaces, strain‑gauge readouts, and bridge circuits. The device is offered in 8‑lead plastic DIP and 8‑lead SOIC packages and meets industrial temperature specifications of –40 °C to +85 °C.
