Product details

What this part is and where it fits

The MAX4080FASA+ is a current-sense amplifier that operates from a 4.5 V to 76 V supply, with 250 kHz bandwidth and 75 µA supply current.

Bandwidth and input offset — measurement accuracy

The 250 kHz bandwidth captures current waveforms in switching converters. The 100 µV input offset and 5 µA input bias set the measurement floor.

Package and mounting

Housed in an 8-pin SOIC package with a 3.90 mm body width, the MAX4080FASA+ is a surface-mount part that reflows alongside standard passive components. The SOIC-8 footprint is widely used and easy to route; the device's pinout places the sense inputs on one side and the output and supply on the other, keeping the high-current sense traces away from the low-level output signal.

Lifecycle and compliance

It is ROHS3 compliant, so it meets current EU and global restrictions on hazardous substances.

Frequently asked questions

Is MAX4080FASA+ suitable for high-side current sensing?

Yes, the MAX4080FASA+ is a current-sense amplifier designed for high-side sensing. Its 76 V maximum supply voltage allows it to monitor current on the high side of a supply rail up to 76 V, and its 250 kHz bandwidth supports fast overcurrent detection.

What is the typical application for MAX4080FASA+?

Typical applications include high-side current sensing in power supplies, battery monitoring, motor control, and telecom equipment. The wide supply range and industrial temperature rating make it suitable for both low-voltage portable gear and high-voltage industrial systems.
