AD8215YRZ

Overview

The AD8215YRZ is a high-voltage current shunt monitor manufactured by Analog Devices Inc. It features a single amplifier channel with a gain error of 0.3% and an input offset voltage of 1 mV. The device operates within a common-mode voltage range of -2 V to 65 V and supports a supply voltage between 4.5 V and 5.5 V. Key electrical parameters include a gain-bandwidth product of 450 kHz, a common-mode rejection ratio of 100 dB, and a power supply rejection ratio of 75 dB. It draws a typical operating supply current of 2.2 mA and functions reliably across a temperature range of -40°C to +125°C in an 8-SOIC package.

Feature Summary

• Supports bidirectional current sensing with a wide common-mode voltage range extending from negative values up to 65 V.
• Provides high accuracy for shunt monitoring applications through a specified gain error of 0.3%.
• Integrates internal precision resistors to establish a fixed gain of 50 V/V without requiring external components.

Applications

• High-side or low-side current sensing in industrial motor drives
• Power supply output current monitoring
• Overcurrent protection circuits in battery management systems

Procurement Notes

Verify the specific suffix YRZ corresponds to the 8-SOIC surface-mount package variant when sourcing. Confirm that the component meets RoHS compliance standards required for your assembly process. Check for availability constraints as distribution channels may report limited stock or restricted sales status for this specific part number. Ensure the ordering information matches the exact manufacturer part number to avoid pinout or specification mismatches.

Selection Notes

Select the AD8215YRZ when designing circuits that require precise current measurement under high common-mode voltages up to 65 V. The fixed 50 V/V gain simplifies design while maintaining a 0.3% gain error for accurate readings. Consider the 450 kHz bandwidth for applications requiring moderate response speeds. The 8-SOIC package offers a compact solution for space-constrained PCB layouts compared to larger packages.

Part Context

The AD8215 belongs to Analog Devices' family of high-voltage current shunt monitors designed for robust performance in demanding environments. This series typically includes variants like the AD8210 and AD8211, which share similar high-voltage capabilities but differ in gain settings and package options. The AD8215 specifically targets applications needing a fixed gain of 50 V/V with tight accuracy specifications.

Replacement Considerations

The AD8215YRMZ serves as a direct replacement offering the same electrical characteristics in an MSOP-8 package. For alternative solutions, consider the AD8210 or AD8211 series, though these may feature different fixed gains such as 20 V/V or 50 V/V respectively. Verify pin compatibility and thermal performance when substituting with other current sense amplifiers.
