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 2.5V 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

operation, and tiny package options make this amplifier

family well suited for use in many general-purpose and

battery-powered applications.
