AD8214WYRMZ

Overview

The AD8214WYRMZ is a single-channel current shunt threshold detector manufactured by Analog Devices Inc. It operates within a supply voltage range of 5 V to 65 V and features a common-mode voltage range from 5 V to 65 V. The device provides a common-mode rejection ratio (CMRR) of 80 dB, with an input bias current of 12 nA and an input offset voltage of 3 mV. It consumes 1.2 mA of operating supply current and functions reliably across a temperature range of -40°C to +125°C. Packaged in an MSOP-8 surface-mount format, it is qualified for automotive applications under AEC-Q100 standards.

Feature Summary

• Functions as a current shunt threshold detector with high common-mode voltage tolerance up to 65 V
• Provides low input bias current and low input offset voltage for accurate detection
• Qualified for automotive applications meeting AEC-Q100 reliability standards

Applications

• High-side current sensing in DC-to-DC converters
• Overcurrent protection circuits
• Automotive power management systems

Procurement Notes

Verify the specific suffix 'WYRMZ' against official Analog Devices documentation to confirm package type and tape/reel specifications. Confirm AEC-Q100 qualification status directly with the manufacturer or authorized distributors, as this certification impacts suitability for automotive-grade designs. Ensure the selected variant matches the required thermal performance for the intended operating environment.

Selection Notes

Select this component when a dedicated threshold detection function is preferred over standard amplification. The AD8214 integrates comparator functionality suitable for overcurrent protection. Compare its 80 dB CMRR and 1.2 mA supply current against alternatives like the AD8210 if buffered output drive is required instead of direct threshold signaling. Evaluate the MSOP-8 footprint constraints against available PCB real estate.

Part Context

This part belongs to the AD8214 series of current shunt threshold detectors. It shares the MSOP-8 package and automotive qualification with other variants in the family but differs in internal configuration compared to general-purpose current sense amplifiers like the AD8212. The 'W' indicates wide temperature range capability, while 'YRMZ' specifies the specific package and reel configuration.

Replacement Considerations

Check for AD8214WYRMZ-R or AD8214WYRMZ-R7 for different packaging options. Verify functional compatibility with AD8210YRZ if buffered output is needed instead of threshold detection.
