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/s 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.
