AD8214ARMZ-R7

Overview

The AD8214ARMZ-R7 is a single-channel current shunt threshold detector manufactured by Analog Devices. It operates within a supply voltage range of 5 V to 65 V and supports a common-mode voltage from 5 V to 65 V. Key electrical specifications 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 draws 1.2 mA of operating supply current and provides a maximum output current of 1 mA per channel. It functions reliably across an extended temperature range from -40°C to +125°C and is housed in an MSOP-8 surface-mount package.

Feature Summary

• Integrated threshold detection capability for direct monitoring of current shunt voltages without external comparator circuitry.
• High common-mode voltage tolerance allowing operation in high-side sensing applications up to 65 V.
• Low power consumption design suitable for battery-operated or energy-constrained systems.

Applications

• Battery management systems for overcurrent protection
• Industrial motor control current limiting
• Power supply overload detection

Procurement Notes

Verify the specific suffix R7 indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the MSOP-8 footprint matches your PCB layout requirements. Check for any recent lifecycle notices regarding availability or obsolescence directly from Analog Devices.

Selection Notes

Select this component when high-side current sensing with integrated threshold logic is required. The wide common-mode range distinguishes it from standard instrumentation amplifiers. Consider the 3 mV offset voltage impact on low-voltage drop measurements. Evaluate the 1.2 mA quiescent current against system power budgets compared to lower-power alternatives.

Part Context

This part belongs to the AD8214 series of current shunt threshold detectors. It shares core functionality with variants like AD8214ARMZ and AD8214ARMZ-RL, differing primarily in packaging format. The series is designed for robust industrial and automotive environments requiring reliable fault detection in power paths.

Replacement Considerations
