Description
The FAN4174 (single) and FAN4274 (dual) are ultra-low
cost voltage feedback amplifiers with CMOS inputs that
consume only 200µA of supply current per amplifier,
while providing ±33mA of output short-circuit current.
These amplifiers are designed to operate from 2.3V 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.
