INA210BIRSWT

Overview

The INA210BIRSWT is a voltage-output, bidirectional current-shunt monitor from the Texas Instruments INA21x series. It utilizes a zero-drift architecture to achieve high precision with an input offset voltage of ±35 µV maximum and a gain of 200 V/V. The device supports a wide common-mode range from –0.3 V to 26 V, independent of the supply voltage. It operates on a single power supply ranging from 2.7 V to 26 V with a maximum quiescent current of 100 µA. The component is housed in a 10-pin Thin UQFN package.

Feature Summary

• Zero-drift topology ensures low offset voltage and minimal drift over temperature for accurate measurements at shunt drops as low as 10 mV full-scale.
• Wide common-mode voltage range allows sensing across shunts at voltages up to 26 V while powered by supplies as low as 2.7 V.
• Fixed internal gain of 200 V/V enables precise current monitoring for system optimization and overcurrent protection.

Applications

• Notebook Computers
• Cell Phones
• Telecom Equipment
• Power Management
• Battery Chargers

Procurement Notes

Verify the specific suffix 'BI' against official documentation to confirm version B characteristics, including the –0.1 V minimum common-mode limit. Ensure the RSWT package designation matches the required 10-pin Thin UQFN form factor. Confirm RoHS compliance status and check for any obsolescence notices or lifecycle changes prior to finalizing procurement plans.

Selection Notes

Select this component when high accuracy is required with minimal shunt dissipation due to its low offset voltage. The fixed 200 V/V gain suits applications needing moderate amplification. Verify that the application's common-mode voltage stays within the specified limits for Version B devices. Consider thermal resistance metrics if operating in enclosed environments.

Part Context

This part belongs to the INA21x family of voltage-output current-shunt monitors. The series includes variants with gains of 50, 75, 100, 500, and 1000 V/V. All models share the zero-drift architecture and wide common-mode range but differ in gain settings and specific electrical tolerances defined by their version letters.
