AD8211YRJZ-R2

Overview

The AD8211YRJZ-R2 is a high-voltage current shunt amplifier manufactured by Analog Devices Inc. It operates within a single-supply voltage range of 4.5 V to 5.5 V and features a common-mode voltage range from -2 V to 65 V. The device provides a gain bandwidth product of 500 kHz, an input offset voltage of 1 mV, and a common-mode rejection ratio of 100 dB. It draws 1.2 mA of operating supply current and maintains a gain error of 0.25%. The component functions across an extended temperature range from -40°C to +125°C and is housed in a compact SOT-23-5 surface-mount package.

Feature Summary

• Supports high common-mode voltages ranging from -2 V to 65 V for flexible shunt placement
• Provides ratiometric output relative to the supply voltage for simplified interfacing
• Delivers buffered output with sufficient drive capability for direct ADC connection

Applications

• High-side current sensing in industrial motor control systems
• Battery management and monitoring in electric vehicle powertrains
• Current protection circuits in DC-to-DC converter topologies

Procurement Notes

Verify the specific suffix R2 indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOT-23-5 thermal characteristics align with the target application's power dissipation requirements. Validate that the 5.5 V maximum supply limit accommodates system voltage transients without exceeding absolute maximum ratings.

Selection Notes

Select this component when a single-supply operation near 5 V is required alongside high common-mode voltage tolerance. The low input offset voltage and high CMRR make it suitable for precision measurements where shunt resistors are placed on the high side of the load. Consider the SOT-23-5 package constraints if board space is limited compared to larger packages like SOIC or MSOP.

Part Context

This part belongs to the AD8211 series of high-voltage current shunt amplifiers. It shares functional similarities with the AD8210 but differs in package type and specific electrical characteristics such as the fixed gain configuration. The series is designed for applications requiring accurate current measurement in noisy environments with high common-mode potentials.

FAQ
