AD8213WHRMZ-R7

Overview

The AD8213WHRMZ-R7 is a dual high-voltage current shunt monitor manufactured by Analog Devices. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a common-mode voltage from -2 V to 65 V. The device features a fixed gain of 20 V/V, a gain bandwidth product of 500 kHz, and a typical input offset voltage of 1 mV. It offers a common-mode rejection ratio of 100 dB and a power supply rejection ratio of 74 dB. The component draws 2.5 mA of operating current and functions reliably across an extended temperature range from -40°C to +150°C. It is housed in a 10-pin MSOP package and is AEC-Q100 qualified for automotive applications.

Feature Summary

• Dual-channel architecture providing independent current sensing capabilities within a single compact package.
• High common-mode voltage tolerance enabling accurate measurements in high-side and low-side configurations up to 65 V.
• Automotive qualification ensuring reliability and performance consistency under rigorous environmental conditions.
• Wide operating temperature range supporting deployment in demanding industrial and automotive thermal environments.

Applications

• Automotive battery management systems
• Motor control circuits
• Industrial power supply monitoring

Procurement Notes

Verify the specific suffix R7 indicates tape-and-reel packaging when sourcing components. Confirm AEC-Q100 automotive qualification status aligns with project requirements. Ensure the MSOP-10 footprint matches the PCB layout design. Cross-reference the datasheet revision date to guarantee parameter accuracy against the manufacturing batch.

Selection Notes

Select this component when dual-channel sensing is required with high common-mode voltage support. The fixed 20 V/V gain simplifies external resistor networks compared to programmable gain alternatives. Consider the 500 kHz bandwidth for applications requiring moderate-speed response. Evaluate the 10-pin MSOP package constraints against available board space and thermal dissipation needs.

Part Context

This part belongs to the AD8213 series of dual current shunt monitors. It shares core specifications with variants like the AD8213YRMZ-R7 but differs in packaging and reel configuration. The WHRMZ designation specifically denotes the automotive-grade version in tube or reel formats depending on the suffix. It complements other Analog Devices signal chain products for comprehensive power management solutions.

Replacement Considerations

The AD8213YRMZ-R7 serves as a functional substitute with identical electrical characteristics. Verify that the alternative package type meets mechanical assembly requirements. Ensure the replacement maintains the same AEC-Q100 qualification level if automotive compliance is mandatory.
