FAN4272AM8X

Instrumentation, Op Amps, Buffer Amps Overview

The FAN4272AM8X is a dual voltage-feedback operational amplifier manufactured by Fairchild Semiconductor. It features a supply current of 130µA per amplifier at 2.7V and a bandwidth of 4MHz. The output swings to within 25mV of either rail, supporting an input voltage range that exceeds the rails. Key electrical parameters include a quiescent current of 130uA, input voltage noise density of 23nV/√Hz@10kHz, and an output current capability of 16mA. The device operates on a supply span from 2.5V to 5.5V with an operating temperature range of -40°C to 125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer marking and date code against Fairchild Semiconductor specifications. Confirm the SOIC-8 package integrity and pin alignment. Ensure the component meets the specified -40°C to 125°C operating temperature range for your application environment. Cross-reference the datasheet revision to confirm parameter consistency.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when rail-to-rail output swing and wide common-mode input range are required in low-power applications. The dual configuration suits space-constrained designs needing two independent amplifiers. Consider the 130µA quiescent current for battery life optimization. Verify that the 4MHz bandwidth meets the signal frequency requirements of the specific circuit topology.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the FAN4272 family of dual operational amplifiers designed for low-voltage, low-power applications. It is housed in an 8-pin SOIC package. The series is characterized by its ability to operate with inputs beyond the supply rails, making it suitable for single-supply systems where signal levels may vary relative to ground.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for direct pin-compatible replacements within the same Fairchild or onsemi portfolio that share identical electrical characteristics and package dimensions. Ensure any substitute maintains the rail-to-rail output and wide input voltage range specifications.
