AD8215WYRZ-RL

Overview

The AD8215WYRZ-RL 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% across the 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. Key electrical specifications include a gain-bandwidth product of 450 kHz, a common-mode rejection ratio (CMRR) of 100 dB, 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 temperature range of -40°C to +125°C.

Feature Summary

• Provides high-side or low-side current sensing capability with a wide common-mode voltage range extending up to 65 V.
• Delivers high precision with a fixed gain of 20 V/V and minimal gain error over the full operating temperature range.
• Offers robust noise immunity through a high common-mode rejection ratio of 100 dB.

Applications

• Industrial process control systems requiring precise current monitoring
• Power supply output current sensing in server and telecom equipment
• Battery management systems for charge/discharge current measurement

Procurement Notes

Verify the specific suffix WYRZ-RL against the official Analog Devices datasheet to confirm package type and reel quantity. Ensure compatibility with system voltage levels and thermal requirements. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status as per the latest manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this component when high common-mode voltage tolerance is required alongside precise gain accuracy. The fixed 20 V/V gain simplifies external resistor selection compared to programmable alternatives. Consider the 450 kHz bandwidth for applications requiring faster transient response than lower-speed monitors. Evaluate the 2.2 mA supply current against total system power budgets.

Part Context

The AD8215 belongs to the AD8215 family of current shunt monitors designed for high-voltage applications. It complements other Analog Devices amplifiers by offering integrated precision without external trimming. The device is part of a broader portfolio of signal chain solutions for industrial and automotive markets.

Replacement Considerations

Check for AD8215 variants with different packaging options such as AD8215YRZ or AD8215YRZ-R7. Verify pinout compatibility and electrical parameter equivalence before substitution.
