Description
The FAN4174 (single) and FAN4274 (dual) are ultra-low cost,
voltage feedback amplifiers with CMOS inputs that consume
only 200 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.

... Overdrive of an amplifier occurs when the output and/or input ranges are exceeded. The recovery time varies based on whether the input or output is overdriven and by how much the ranges are exceeded. The FAN4174 will typically recover in less than 500ns from an overdrive condition.
