AD8210WYRZ

Overview

The AD8210WYRZ is a high-voltage, bidirectional current shunt monitor manufactured by Analog Devices Inc. It operates with a common-mode voltage range from −2 V to +65 V and withstands survival voltages up to +68 V. The device features a fixed gain of 20 V/V, providing a ratiometric half-scale output offset for simplified interface with analog-to-digital converters. It offers excellent AC and DC performance, including a typical CMRR of 120 dB at DC and 80 dB at 100 kHz. The part supports a wide operating temperature range from −40°C to +125°C and includes buffered output drive capability of 5 mA.

Feature Summary

• Supports bidirectional current sensing with a high common-mode voltage range extending to +65 V
• Provides a ratiometric half-scale output offset suitable for direct ADC interfacing
• Features high common-mode rejection ratio for accurate signal measurement in noisy environments
• Includes robust ESD protection rated at ±4000 V HBM

Applications

• Current sensing in motor control systems
• Transmission controls in automotive applications
• Diesel injection controls
• Engine management systems
• DC-to-DC converters

Procurement Notes

Verify the specific suffix WYRZ against official Analog Devices documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with system voltage requirements, specifically the 2 V to 65 V common-mode range. Confirm that the fixed 20 V/V gain meets the design sensitivity needs without external resistor adjustments. Check for AEC-Q100 qualification if automotive reliability standards are required for the application environment.

Selection Notes

Select this component when a fixed gain of 20 V/V is required for bidirectional current monitoring. It is suitable for designs needing a ratiometric output relative to the supply voltage. Consider this part for applications requiring high common-mode voltage tolerance up to 65 V. Evaluate the 120 dB DC CMRR for noise immunity requirements. Verify that the 5 mA output drive capability is sufficient for the connected load impedance.

Part Context

The AD8210 belongs to the AD821x series of high-voltage current shunt monitors designed for industrial and automotive use. It complements other devices like the AD8211 and AD8212, which offer adjustable gains or different bandwidth characteristics. This series addresses the need for precise current measurement in high-side configurations where ground reference is not available. The AD8210 provides a cost-effective solution with integrated precision resistors and buffered outputs.

Replacement Considerations

Check Analog Devices datasheets for pin-compatible alternatives within the AD821x family. Verify if the AD8211 or AD8212 variants meet the gain and bandwidth requirements. Ensure any substitute maintains the same common-mode voltage range and package dimensions.
