AD8214ARMZ-RL

Overview

The AD8214ARMZ-RL is a single-channel current shunt threshold detector manufactured by Analog Devices Inc. It operates within a supply voltage range of 5 V to 65 V and supports common-mode voltages from 5 V to 65 V. Key electrical parameters include an input bias current of 12 nA, an input offset voltage of 3 mV, and a common-mode rejection ratio of 80 dB. The device consumes 1.2 mA of operating power and functions reliably across a temperature range of -40°C to +125°C. It is housed in an MSOP-8 surface-mount package.

Feature Summary

• Integrated high-side current sensing with built-in threshold detection capabilities
• Wide common-mode voltage range supporting high-voltage applications up to 65 V
• Low input bias current for improved measurement accuracy
• Robust performance across extended industrial temperature ranges

Applications

• High-side current monitoring in industrial systems

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm the specific suffix matches the required reel or cut tape packaging variant. Ensure the MSOP-8 footprint aligns with the target PCB design. Cross-reference the datasheet revision date against manufacturing lot codes to guarantee compliance with current specifications.

Selection Notes

Select this component when high-side current sensing with integrated threshold logic is required. The wide common-mode voltage range makes it suitable for high-voltage environments where standard amplifiers may fail. Consider the low quiescent current for power-sensitive designs. Verify that the MSOP-8 package dimensions fit the available board space constraints.

Part Context

This part belongs to the AD8214 series of current sense amplifiers designed for robust operation in demanding environments. It integrates precision amplification with threshold detection to simplify circuit design. The device is optimized for applications requiring reliable current monitoring without external comparator components.

Replacement Considerations

Check for AD8214 variants with different suffixes for packaging changes. Verify pin compatibility before substituting with other Analog Devices current sense amplifiers.
