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 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.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Functional operation under any of these conditions is NOT implied. Performance and reliability are guar anteed only if operating conditions are not exceeded. Symbol Parameter Min. Max.
