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.
