Product details

Current sense amplifier for shunt-based measurements

The Analog Devices MAX4173TESA+ is a single-channel current sense amplifier designed to measure current through an external shunt resistor. It operates from a 3 V to 28 V supply span. The 1.7 MHz bandwidth is enough to capture current waveforms in switching converters and motor drives running at moderate PWM frequencies. Supply draw is 420 µA, which keeps the thermal contribution low in a dense board.

Industrial temperature range and package

Rated for -40°C to 85°C, this part suits factory-floor automation, outdoor telecom enclosures, and engine-bay electronics where the ambient can climb. The 8-SOIC package is a standard footprint for current-sense amplifiers; it sits on the same land pattern as many general-purpose op-amps, so a layout change is minimal when swapping in a dedicated sense part. Mounting is surface-mount, which keeps assembly compatible with reflow processes.

Lifecycle and sourcing

The MAX4173TESA+ carries an Active lifecycle status with ROHS3 compliance. For BOM planning, this part is not subject to a last-time-buy window; it can be specified into new designs with confidence that supply will continue.

Frequently asked questions

What is the bandwidth of MAX4173TESA+?

The -3 dB bandwidth is 1.7 MHz. This is sufficient for monitoring current in switching power supplies and motor drives with PWM frequencies up to several hundred kilohertz.

Can MAX4173TESA+ be used for high-side current sensing?

Yes, as a current sense amplifier, it is intended for both high-side and low-side shunt measurements. The 28 V common-mode range supports high-side sensing on typical industrial and automotive rails.

Where can I buy MAX4173TESA+ available via RFQ confirmation?

This part is available to order through independent distribution. Submit an RFQ for current availability and pricing; stock and lead time are confirmed at quote time.
