FAN4174/FAN4274 are ultra-low cost, rail-to-rail I/O, CMOS amplifiers with 200µA supply current, 3.7MHz bandwidth, 10mV output swing, 3V/µs slew rate, 25nV/√Hz noise voltage.
The FAN4174 (single) and FAN4274 (dual) are ultra‑low‑cost voltage‑feedback CMOS amplifiers designed for 2.5 V to 5 V supplies. They feature rail‑to‑rail I/O, low supply current, and high bandwidth, making them suitable for portable, battery‑powered applications such as mobile communications, sensor interfaces, and active filters.
The document includes detailed electrical specifications at both +2.7 V and +5 V supply levels, pin‑out diagrams for SOT23‑5 and MSOP‑8 packages, reliability data, ordering information, and typical performance graphs covering frequency response, distortion, and power‑supply rejection.
