±0.25% accuracy current monitor for automotive and industrial rails
The AD8213WYRMZ from Analog Devices is a dual-channel current monitor in the Automotive series, designed for high- and low-side shunt sensing across a -2V to 65V input range. Its ±0.25% accuracy holds over the full -40°C to 125°C temperature range, making it a fit for motor-drive phase current monitoring, solenoid control, and battery-rail sensing in automotive ECUs and industrial drives. The 10-MSOP package keeps the board footprint small for dense power-stage layouts.
Input voltage range — high-side and low-side flexibility
The -2V to 65V common-mode input range covers both high-side (above the supply rail) and low-side (near ground) shunt placements without level shifting. This matters when the sense resistor sits on the battery line or the low-side return of a half-bridge — the monitor handles the swing without external clamping. The negative input capability down to -2V handles inductive kickback transients common in motor-drive environments.
Temperature grade and automotive qualification
Rated for -40°C to 125°C operation, the AD8213WYRMZ is specified for under-hood and engine-bay thermal profiles. The Automotive series designation implies AEC-Q100 qualification (confirm with the full datasheet), which is the standard for Tier-1 automotive supply chains. The active lifecycle status means no last-time-buy risk for current production runs — this part is still in the factory catalog.
Package and handling
Supplied in a 10-MSOP package (3.00 mm width) on Tube. Surface-mount assembly with standard MSOP-10 footprint. No exposed pad, so thermal dissipation is through the leads — keep the ambient within the 125°C limit for continuous operation.
