Product details

The Analog Devices MAX4173FESA+ is a single-channel current sense amplifier in an 8-SOIC package, designed to measure load current by amplifying the voltage across an external shunt resistor. It operates from a 3 V to 28 V supply span. The 1.4 MHz bandwidth captures fast load transients and switching ripple. Supply current is 420 µA.

Package and mounting

Surface-mount 8-SOIC (0.154", 3.90 mm width) — standard footprint, reflow-friendly. Supplied in Tube; if your pick-and-place line prefers Tape & Reel, verify the reel option or plan a tube-to-reel transfer. The -40°C to 85°C operating range covers industrial and commercial environments; not rated for extended automotive or downhole temperatures.

Frequently asked questions

What is the bandwidth of MAX4173FESA+?

The -3 dB bandwidth is 1.4 MHz.

Can MAX4173FESA+ replace MAX4172?

The MAX4173FESA+ and MAX4172 are both current sense amplifiers in the same family with similar pinout, but verify the bandwidth and input offset voltage against your design — the MAX4173FESA+ has a 1.4 MHz bandwidth and 300 µV input offset.

What is the pin configuration of MAX4173FESA+?

The part is a single-circuit current sense amplifier in an 8-SOIC package. Refer to the datasheet for the full pinout diagram.
