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.
