AD8212WYRMZ

Overview

The AD8212WYRMZ is a high-voltage current shunt monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 7 V to 65 V and supports common-mode voltages from 7 V to 65 V. The device features an adjustable gain, a gain-bandwidth product of 1 MHz, and a common-mode rejection ratio of 100 dB. Key electrical parameters include an input bias current of 200 uA, an input offset voltage of 2 mV, and a maximum gain error of 1%. It consumes 720 uA of operating power and functions reliably across a temperature range of -40 C to +125 C. The component is housed in an MSOP-8 package and holds AEC-Q100 qualification.

Feature Summary

• Supports high common-mode voltage operation up to 65 V for high-side sensing
• Features adjustable gain configuration for flexible signal conditioning
• Provides high common-mode rejection ratio for accurate measurements in noisy environments
• Qualified for automotive applications under AEC-Q100 standards

Applications

• High-side current monitoring in industrial systems
• Current sensing in DC-to-DC converters
• Motor control circuit protection
• Power supply overcurrent detection

Procurement Notes

Verify the specific suffix WYRMZ against official Analog Devices documentation to confirm package type and temperature grade. Confirm AEC-Q100 automotive qualification status if required for your design. Check availability through authorized distributors as stock levels vary. Ensure the ordering information matches the exact part number to avoid functional discrepancies with similar variants in the AD8212 series.

Selection Notes

Select this component when high common-mode voltage tolerance is required alongside adjustable gain capabilities. Compare operating current consumption against low-power alternatives if battery life is critical. Verify that the MSOP-8 package fits the PCB layout constraints. Consider the 1 MHz bandwidth for dynamic response requirements in switching applications.

Part Context

This device belongs to the AD8212 series of high-voltage current shunt monitors. It shares core specifications with variants like the AD8212YRMZ but differs in packaging and specific manufacturing details. The series is designed for robust current sensing in harsh electrical environments where standard amplifiers may fail due to high common-mode voltages.

Replacement Considerations

The AD8212YRMZ is a related variant within the same series. Verify pinout compatibility and package dimensions before substitution. Check if the fixed gain of the YRMZ variant meets the application requirements instead of the adjustable gain of the WYRMZ.
