Description
The FAN4174 is a single, ultra-low cost, voltage feedback
amplifier with CMOS inputs that consumes only 200µA of
supply current while providing ±33mA of output short
circuit current. The FAN4174 is designed to operate from
2.5V to 5V supplies. The common mode voltage range
extends beyond the negative and positive rails.
The FAN4174 is designed on a CMOS process and provides
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 the FAN4174 well suited for use in many gen-
eral purpose and battery powered applications.
