Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at

Description
The FAN4174 (single) and FAN4274 (dual) are voltage
feedback amplifiers with CMOS inputs that consume
only 200 µA of supply current per amplifier, while
providing ±33 mA of output short-circuit current. These
amplifiers are designed to operate 5 V 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 3.7 MHz of bandwidth and 3 V /
μs
of slew rate at a supply voltage of 5 V.
These amplifiers operate and are reliable over a wide
temperature range of -40°C to +125°C.
The combination of extended temperature operation,
low power, rail-to-rail performance, low-voltage
operation, and a tiny package optimize this amplifier
family for use in many industrial, general-purpose, and
