Product details

Current sense amp for the bench and the board

The Maxim Integrated MAX4173HESA+T is a single-channel current sense amplifier in an 8-SOIC package. It monitors current by amplifying the voltage drop across an external shunt resistor, outputting a voltage proportional to the load current. Key specs: 1.2 MHz bandwidth, 420 µA supply current, and a supply span from 3 V to 28 V. It's built for industrial temperature range (-40°C to 85°C) and is fully RoHS3 compliant.

Package and mounting

8-SOIC is a standard footprint, easy to hand-solder or reflow. The 3.90 mm body width fits common SOIC-8 land patterns. No hidden thermal pad — the part dissipates through the leads, which is fine for a 420 µA amplifier.

Lifecycle and sourcing posture

The MAX4173HESA+T carries an Active product status with no last-time-buy or NRND flags. It is RoHS3 compliant. For BOM planning, this part is suitable for new designs and ongoing production.

Frequently asked questions

Is MAX4173HESA+T RoHS compliant?

Yes, it is ROHS3 Compliant.

What are the alternatives to MAX4173HESA+T if it is out of stock?

The MAX4173 series includes multiple gain options (T, F, H) in the same 8-SOIC footprint, but the evidence does not list a specific pin-compatible alternate. For supply resilience, contact us to confirm availability or discuss a second-source option.
