INA211CIDCKT

Overview

The INA211CIDCKT is a bidirectional, zero-drift current shunt monitor from Texas Instruments. It features a voltage output and supports both low-side and high-side measurements. The device operates with a single supply voltage ranging from +2.7V to +26V. It detects common-mode voltages from -0.3V to 26V. The input offset voltage is typically 5µV. The gain bandwidth product is 40kHz. The maximum operating temperature is +85°C. The minimum operating temperature is -40°C. The package type is SC-70-6.

Feature Summary

• Zero-drift architecture ensures low offset for accurate sensing across small shunt voltage drops.
• Bidirectional capability allows detection of current flow in both directions.
• Supports both high-side and low-side current monitoring configurations.

Applications

• Battery management systems
• Overcurrent protection circuits
• Load switch control

Procurement Notes

Verify the specific suffix 'CKT' against the manufacturer's official documentation to confirm the tape-and-reel packaging configuration and quantity. Ensure the industrial temperature grade (C) aligns with the thermal requirements of the target application environment before finalizing procurement orders.

Selection Notes

Select this component when precise DC current measurement is required without external calibration. The zero-drift technology minimizes errors caused by temperature variations. Verify that the fixed gain meets the system's dynamic range requirements for the expected shunt voltage levels.

Part Context

This part belongs to the INA21x family of current shunt monitors. These devices are designed for applications requiring high accuracy and stability. The family offers various gain options and package types to suit different board space and performance needs.

Replacement Considerations

Check the INA210 or INA211 variants for alternative gain settings or package options. Confirm pin compatibility and electrical specifications match the existing design constraints before substituting.
