AD8215WYRZ-R7

Overview

The AD8215WYRZ-R7 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 operates with a supply voltage between 4.5 V and 5.5 V and supports a common-mode voltage range from -2 V to +65 V. Key electrical specifications include a bandwidth of 450 kHz, an input offset voltage of 1 mV, and a power supply rejection ratio (PSRR) of 75 dB. It draws a typical operating supply current of 2.2 mA and functions within a junction temperature range of -40°C to +125°C.

Feature Summary

• Provides high-precision current monitoring with a fixed internal gain of 20 V/V for simplified circuit design.
• Supports wide common-mode voltage inputs ranging from -2 V to +65 V, enabling use in high-side configurations.
• Delivers high common-mode rejection ratio (CMRR) of 100 dB to ensure accurate measurements in noisy environments.

Applications

• High-side current sensing in industrial automation systems
• Battery management and protection circuits in portable devices
• Overcurrent detection in motor control applications

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. to avoid counterfeit components. Check RoHS compliance status via official documentation. Ensure the part number matches exactly, as variations exist in the AD8215 family. Validate authenticity through authorized distribution channels.

Selection Notes

Select this component when a fixed 20 V/V gain is required for high-voltage shunt monitoring. It is suitable for applications needing a wide common-mode range up to 65 V. Consider the 450 kHz bandwidth for dynamic signal requirements. Evaluate the 2.2 mA supply current against power constraints. Compare against adjustable gain alternatives if flexibility is needed.

Part Context

This part belongs to the AD8215 series of current sense amplifiers. It shares the core architecture with variants like AD8215YRZ but differs in packaging and tape-and-reel configuration. The series is designed for precision measurement in harsh electrical environments. It complements other ADI current monitors offering different gain settings or package types.

Replacement Considerations

Direct substitutes include AD8215YRZ and AD8215WYRZ. Verify pin compatibility and gain accuracy before substitution. Check if alternative packages meet spatial constraints. Ensure thermal performance remains adequate for the application environment.
