Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix FAUT against official manufacturer documentation to confirm pinout compatibility and electrical tolerances. Confirm availability status through authorized distributors as supply conditions may vary. Ensure the SC-70-5 package footprint matches the target PCB layout requirements before finalizing procurement decisions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high-side sensing is required within a 3 V to 28 V common-mode range. The 1.7 MHz bandwidth supports moderate-speed transient detection needs. Consider the 500 uA quiescent current for battery-powered designs where low standby power is critical but higher than ultra-low-power alternatives.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4073 series of current sense amplifiers designed for cost-sensitive applications. The series provides voltage-output solutions for monitoring current flow in high-side configurations. The FAUT variant specifically denotes the SC-70-5 surface-mount packaging option suitable for compact circuit board designs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult official substitution guides for compatible alternatives such as other members of the MAX4073 family or equivalent high-side amplifiers from Analog Devices. Verify that any substitute maintains the required 28 V common-mode voltage rating and SC-70-5 package dimensions.
