INA210BIRSWR

Overview

The INA210BIRSWR is a zero-drift current shunt monitor manufactured by Texas Instruments. It features a fixed gain of 200 V/V and supports bidirectional current sensing with voltage outputs for both high-side and low-side measurements. The device operates within a supply voltage range of 2.7 V to 26 V and draws a typical operating supply current of 100 µA. Key electrical specifications include a maximum input offset voltage of 550 nV, an input bias current of 28 µA, and a gain error of 0.02%. It provides a common-mode rejection ratio (CMRR) of 140 dB and functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Zero-drift architecture ensures minimal offset voltage drift over temperature variations
• Supports bidirectional current measurement with flexible high-side or low-side output configurations
• High precision performance with fixed internal gain and ultra-low input offset voltage

Applications

• Battery management systems requiring precise current monitoring
• Industrial process control loops with shunt-based sensing
• Overcurrent protection circuits in power distribution units

Procurement Notes

Verify the specific suffix 'BIRSWR' against the official Texas Instruments datasheet to confirm the exact grade, package type, and tape-and-reel specifications. Ensure compatibility with your PCB footprint for the UQFN-10 package. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this component when high accuracy and stability are required without external trimming. The fixed 200 V/V gain simplifies design by eliminating external resistors. Consider the 100 µA supply current for battery-powered applications. Verify that the 12 V common-mode voltage limit meets your system requirements. The UQFN-10 package offers a compact solution for space-constrained designs.

Part Context

The INA210 belongs to Texas Instruments' Zero-Drift series of current shunt monitors. This family is designed to replace traditional amplifiers that require periodic calibration. The INA210 specifically integrates chopper stabilization technology to maintain low offset voltages over time and temperature, distinguishing it from standard operational amplifier solutions in current sensing applications.

Replacement Considerations

Check the INA210 datasheet for direct pin-compatible alternatives within the same series. Verify if other suffixes like INA210AIRSWR meet the specific temperature and accuracy grades required for your application.
