The AD8278 and AD8279 are general‑purpose difference amplifiers intended for precision signal‑conditioning in power‑critical applications. They feature a wide input range beyond the supplies, rugged over‑voltage protection, low supply current (200 µA for AD8278, 300‑350 µA for AD8279) and a bandwidth of 1 MHz at a gain of ½.
The datasheet provides detailed specifications, absolute maximum ratings, thermal resistance data, pin‑out diagrams, typical performance curves, and ordering information for the available 8‑lead MSOP, 8‑lead SOIC and 14‑lead SOIC packages.
| Bandwidth (G = ½) | 1 MHz |
|---|---|
