Description
The FAN4174 (single) and FAN4274 (dual) are ultra-low cost, voltage feedback amplifiers with CMOS inputs that consume only 200 µ A of supply current per amplifier while providing ±33mA of output short circuit current. These amplifiers are designed to operate from 2.5V to 5V 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 3.7MHz of bandwidth and 3V/µs of slew rate at a supply voltage of 5V. The combination of low power, rail-to-rail performance, low voltage operation, and tiny package options make this amplifier family well suited for use in many general purpose and battery powered applications.
