INA210AIDCKT

Overview

The INA210AIDCKT is a single-channel, bi-directional current shunt monitor from Texas Instruments featuring a zero-drift architecture. It operates within a supply voltage range of 2.7 V to 26 V and supports both high-side and low-side measurements. The device provides a fixed gain of 200 V/V with an input offset voltage of 550 nV and a gain error of 0.02%. Key electrical specifications include a common-mode rejection ratio (CMRR) of 140 dB, a gain-bandwidth product of 14 kHz, and a quiescent current of 100 µA. It functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Zero-drift technology ensures minimal input offset voltage drift over time and temperature variations.
• Bi-directional capability allows for accurate measurement of current flow in both directions.
• Supports flexible system integration through compatibility with both high-side and low-side current sensing configurations.

Applications

• Battery management systems requiring precise current monitoring
• Industrial process control loops
• Power supply output current regulation

Procurement Notes

Verify the specific suffix 'CKT' corresponds to the SC-70-6 package and tape-and-reel quantity configuration as defined by Texas Instruments documentation. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly planning. Ensure the selected variant matches the required gain and package type for the target design.

Selection Notes

Select this component when high precision is required without external calibration due to its zero-drift characteristics. The fixed 200 V/V gain suits applications with small shunt voltages. Consider the SC-70-6 package constraints for board space. Verify that the 14 kHz bandwidth meets the dynamic response needs of the application.

Part Context

This part belongs to the INA210 series of current shunt monitors designed for high-accuracy applications. The series utilizes chopper stabilization to achieve ultra-low offset voltages. The INA210AIDCKT specifically denotes the A-grade version in a compact surface-mount package, offering improved accuracy compared to standard grades.

Replacement Considerations

INA210BIDCKT offers similar functionality with potentially different grade specifications. INA210AIRSWT provides the same core performance but in a UQFN-10 package. Verify pinout and thermal requirements when substituting.
