AD8215WYRZ

Overview

The AD8215WYRZ is a high-voltage, precision current shunt monitor manufactured by Analog Devices Inc. It features a fixed gain of 20 V/V with a maximum gain error of ±0.3% over the full temperature range. The device supports a common-mode voltage range from -2 V to 65 V and operates on a single supply voltage between 4.5 V and 5.5 V. It draws a typical supply current of 2.2 mA and offers a gain-bandwidth product of 450 kHz. The component is housed in an 8-lead SOIC package and is qualified for operation across an extended temperature range of -40°C to +125°C.

Feature Summary

• Provides high-precision current sensing with a fixed gain of 20 V/V and minimal gain error across wide temperature variations.
• Supports bidirectional or unidirectional high-voltage common-mode signals ranging from -2 V to 65 V.
• Integrates low power consumption with a typical supply current of 2.2 mA for efficient system operation.

Applications

• High-side and low-side current monitoring in industrial automation systems
• Battery management and protection circuits in electric vehicles
• Power supply current limiting and regulation in server infrastructure

Procurement Notes

Verify the specific suffix (WYRZ) against the manufacturer's latest datasheet to confirm package type, tape-and-reel quantity, and automotive qualification status. Ensure compatibility with your PCB footprint and reflow profile requirements. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm RoHS compliance and lead time availability directly with the supplier before finalizing procurement orders.

Selection Notes

Select this component when precise current measurement is required in high-common-mode voltage environments. The fixed 20 V/V gain simplifies external resistor networks, reducing board space and design complexity. Consider the 450 kHz bandwidth for applications requiring moderate response speeds. Evaluate the 8-SOIC package constraints against available PCB real estate and thermal dissipation needs compared to alternative packages like MSOP.

Part Context

The AD8215 belongs to Analog Devices' AD821x family of current shunt monitors, designed for robust performance in demanding industrial and automotive applications. This series emphasizes accuracy and high common-mode rejection, making it suitable for critical monitoring tasks where signal integrity under high voltage stress is essential. The WYRZ variant specifically denotes the SOIC-8 packaging and reel configuration.

Replacement Considerations

Direct substitutes include other parts within the AD821x family, such as the AD8210 or AD8211, depending on gain and voltage requirements. Verify pinout compatibility and electrical specifications before swapping. Alternative manufacturers may offer similar current sense amplifiers, but ensure common-mode voltage ranges and gain errors match the original design constraints.
