AD8211YRJZ-RL

Overview

The AD8211YRJZ-RL is a high voltage, precision current shunt amplifier manufactured by Analog Devices Inc. It features a fixed gain of 20 V/V with a typical gain error of ±0.35% over the full temperature range. The device supports a common-mode input voltage range from -2 V to +65 V, independent of the 5 V supply. Key electrical parameters include a 500 kHz gain-bandwidth product, 120 dB typical common-mode rejection ratio (CMRR), and 1 mV maximum input offset voltage. It operates on a single 4.5 V to 5.5 V supply with a quiescent current of 2 mA. The component is housed in a 5-lead SOT-23 package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides unidirectional current measurement across a shunt resistor with a buffered output voltage that directly interfaces with standard analog-to-digital converters.
• Delivers excellent common-mode rejection performance across a wide voltage range from -2 V to +65 V while maintaining stability with a 5 V supply.
• Features high accuracy with low offset drift and minimal gain variation over temperature, suitable for precision industrial applications.

Applications

• Motor control systems
• Solenoid control circuits
• Battery management systems
• DC-to-DC converters

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm RoHS compliance status and check for automotive qualification documentation if required for specific industrial or vehicle dynamic control applications. Ensure storage conditions align with manufacturer specifications to maintain device integrity prior to assembly.

Selection Notes

Select this component for high-side current sensing applications requiring a wide common-mode voltage range up to 65 V. The fixed 20 V/V gain simplifies design by eliminating external resistor networks. Consider the SOT-23-5 package for space-constrained layouts. Verify that the 2 mA quiescent current meets system power budget requirements compared to lower-power alternatives.
