FAN4274: Single and Dual, Rail-to-Rail I/O, CMOS Amplifier

The FAN4174 (single) and FAN4274 (dual) are voltage feedback amplifiers with CMOS inputs that consume only 200 µA of supply current per amplifier, while providing ±33 mA of output short-circuit current. These amplifiers are designed to operate 5 V supplies. The common mode voltage range extends beyond the negative and positive rails.

The FAN4174 and FAN4274 are designed on a CMOS process and provide 3.7 MHz of bandwidth and 3 V / μs of slew rate at a supply voltage of 5 V.

These amplifiers operate and are reliable over a wide temperature range of -40°C to +125°C.

The combination of extended temperature operation, low power, rail-to-rail performance, low-voltage operation, and a tiny package optimize this amplifier family for use in many industrial, general-purpose, and battery-powered applications.
