INA210AIRSWR

Overview

The INA210AIRSWR is a unidirectional current shunt monitor manufactured by Texas Instruments, featuring a fixed gain of 200 V/V. It operates within a supply voltage range of 2.7 V to 26 V and consumes 100 uA of quiescent current. The device provides high accuracy with a maximum gain error of 0.02% and a common-mode rejection ratio of 140 dB. It supports a common-mode voltage of 12 V and has an input bias current of 28 uA. The input offset voltage is specified at 550 nV, and the gain-bandwidth product is 14 kHz. It functions in temperatures from -40 C to +125 C and is housed in a UQFN-10 package.

Feature Summary

• Zero-drift architecture ensures low input offset voltage and minimal drift over temperature variations.
• High common-mode rejection ratio maintains signal integrity in noisy environments.
• Fixed internal gain eliminates the need for external precision resistors.

Applications

• Industrial process control systems
• Power management circuits
• Battery monitoring applications

Procurement Notes

Verify the specific suffix 'AIRSWR' against the manufacturer's official datasheet to confirm the exact grade, temperature range, and packaging configuration. Ensure compatibility with the target PCB footprint for the UQFN-10 package. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a fixed 200 V/V gain is required for unidirectional current sensing. It is suitable for applications demanding high precision and stability without external calibration. Consider the 12 V common-mode limit and 2.7 V minimum supply voltage during system design. Evaluate the UQFN-10 package size against available board space constraints.

Part Context

This device belongs to the INA210 series of current shunt monitors from Texas Instruments. It shares architectural similarities with other zero-drift amplifiers in the family but is distinguished by its specific fixed gain and unidirectional output characteristics. The series is designed for high-accuracy measurement applications requiring stable performance across wide temperature ranges.

Replacement Considerations

INA210AIRSWT is a tape-and-reel alternative within the same series offering identical electrical specifications and functionality.
