INA210AIDCKJ

Overview

The INA210AIDCKJ 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 operates on a single supply voltage ranging from 2.7 V to 26 V, drawing a maximum quiescent current of 100 µA. It supports common-mode voltages from –0.3 V to 26 V, enabling low-side or high-side measurements independent of the supply rail. The component is housed in a 6-pin SC-70 package.

Feature Summary

• Zero-drift topology ensures high accuracy with minimal offset voltage drift over temperature.
• Capable of sensing shunt drops as low as 10 mV full-scale for reduced power dissipation.
• Supports bidirectional current measurement across wide common-mode voltage ranges.

Applications

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

Procurement Notes

Verify the specific suffix 'J' against the manufacturer's official orderable addendum to confirm package type and availability status. Confirm RoHS compliance and moisture sensitivity levels prior to integration. Ensure the design accounts for the specified operating temperature range and absolute maximum ratings to maintain reliability.

Selection Notes

Select this component when precise current monitoring is required with minimal shunt voltage drop. The fixed 200 V/V gain suits applications where moderate amplification is needed. Consider the SC-70 package size for space-constrained designs. Verify that the system's common-mode voltage remains within the specified limits relative to the supply voltage.

Part Context

This part belongs to the INA21x family of current-shunt monitors, which includes variants with different fixed gains (INA211 through INA215). All members share the same zero-drift architecture, pinout compatibility, and general electrical characteristics, differing primarily in their internal gain settings and specific version tolerances.

Replacement Considerations

Direct substitutes within the same family include INA210AIDCKR and INA210AIRSWT. These parts share identical electrical specifications and functionality but may differ in packaging options or manufacturing lot revisions. Verify package dimensions and marking codes before substitution.
