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.","metaTitle":"MAX4173TESA+ Current Sense Amplifier, 1.7 MHz, 8-SOIC","metaDescription":"MAX4173TESA+ current sense amplifier from Analog Devices. 3 V to 28 V supply, 1.7 MHz bandwidth, 420 µA supply current.
