AD8212WYRMZ-R7

Overview

The AD8212WYRMZ-R7 is a high-voltage current shunt monitor with adjustable gain, manufactured by Analog Devices Inc. It operates within a supply voltage range of 7 V to 65 V and supports a common-mode voltage from 7 V to 65 V. The device features a gain-bandwidth product of 1 MHz, a common-mode rejection ratio of 100 dB, and a power supply rejection ratio of 80 dB. Input characteristics include an input bias current of 200 uA and an input offset voltage of 2 mV. Quiescent current is 720 uA, with a gain error of 1%. It functions in temperatures from -40°C to +125°C, is AEC-Q100 qualified, and is packaged in MSOP-8 tape and reel.

Feature Summary

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

Applications

• High-side current monitoring in industrial systems

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm AEC-Q100 qualification status matches project requirements. Ensure the MSOP-8 package footprint aligns with PCB layout constraints. Cross-reference the datasheet for thermal performance limits in enclosed environments.

Selection Notes

Select this component for applications requiring high common-mode voltage tolerance and adjustable gain. Compare quiescent current specifications against low-power alternatives if energy efficiency is critical. Verify that the 1 MHz bandwidth meets the signal frequency requirements of the target application.

Part Context

This part belongs to the AD8212 series of high-voltage current shunt monitors. It shares functional similarities with the AD8212YRMZ but differs in packaging format. The W suffix typically denotes specific temperature or automotive grades within the Analog Devices portfolio.

Replacement Considerations

The AD8212YRMZ serves as a tube-packaged alternative with identical electrical specifications. Verify pin compatibility and package dimensions before substitution.
