AD8215YRZ-RL

Overview

The AD8215YRZ-RL is a single-channel current sense amplifier from Analog Devices, housed in an SOIC-8 surface-mount package. It operates with a supply voltage range of 4.5 V to 5.5 V and draws a typical quiescent current of 2.2 mA. The device supports bidirectional current sensing with a common-mode voltage range extending from -2 V to 65 V. Key electrical specifications include a gain error of 0.15%, a gain bandwidth product of 450 kHz, and a common-mode rejection ratio of 100 dB. It functions reliably within an operating temperature range of -40°C to +125°C.

Feature Summary

• Supports bidirectional current monitoring across a wide common-mode voltage range
• Provides high accuracy with low gain error specification
• Features high common-mode rejection for noise immunity
• Operates on a single low-voltage power supply

Applications

• High-side or low-side current sensing in industrial systems
• Battery management and protection circuits
• Motor control applications requiring precise current feedback
• Power supply overcurrent protection designs

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and reel configuration. Ensure compatibility with your PCB footprint and reflow profile requirements. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through the latest datasheet revision. Validate that the supply voltage and common-mode ranges match your system design constraints before procurement.

Selection Notes

Select this component when a single-supply operation is required alongside high common-mode voltage tolerance. The 450 kHz bandwidth suits applications needing moderate speed without excessive power consumption. Compare the 0.15% gain error against stricter precision requirements where other family members might be necessary. Consider the SOIC-8 package availability relative to space-constrained designs. Evaluate the 2.2 mA quiescent current against battery-powered efficiency targets.

Part Context

This device belongs to the AD8215 series of current shunt monitors designed for high-voltage environments. It integrates precision amplification stages to accurately measure voltage drops across shunt resistors. The series is engineered for robust performance in noisy industrial settings. Analog Devices utilizes advanced silicon processes to achieve low offset and high CMRR. This specific variant offers a balance of speed and accuracy for general-purpose monitoring tasks.

Replacement Considerations

Check the official Analog Devices website for direct pin-compatible alternatives within the same series. Verify if updated revisions have superseded this specific reel version. Ensure any substitute maintains the 65 V common-mode limit and SOIC-8 footprint. Consult the manufacturer's cross-reference guide for validated replacements.
