INA210CIDCKT

Overview

The INA210CIDCKT is a voltage-output, bidirectional zero-drift current shunt monitor manufactured by Texas Instruments. It detects voltage drops across shunt resistors within a common-mode voltage range of -0.3V to 26V, independent of the supply voltage. The device operates on a single power supply ranging from +2.7V to +26V and consumes a maximum of 100µA of supply current. It features a fixed gain configuration with a maximum input offset voltage of ±50µV and a maximum offset drift of 0.5µV/°C. The component supports high-side or low-side measurements and functions reliably across an extended temperature range of -40°C to +125°C.

Feature Summary

• Zero-drift architecture ensures low offset voltage for accurate sensing at small full-scale shunt voltage drops down to 10mV.
• Bidirectional capability allows detection of current flow in both directions relative to the ground reference.
• Independent operation from supply voltage enables monitoring across a wide common-mode voltage span.

Applications

• Battery management systems in portable electronics
• Power management circuits in telecommunications equipment
• Current monitoring in battery chargers

Procurement Notes

Verify the specific suffix 'CIDCKT' against the official datasheet to confirm the exact gain value, as the base part number covers multiple gain options. Ensure the package type matches the SC-70-6 specification. Confirm that the C-grade offset specifications meet the design requirements before finalizing the order.

Selection Notes

Select this component when precise current measurement is required at low voltage drops without complex calibration. The zero-drift technology minimizes errors caused by temperature variations. Consider the fixed gain option that best matches the expected shunt resistor value and desired output voltage swing for the application.

Part Context

This part belongs to the INA21x series of current shunt monitors from Texas Instruments. The series includes variants with different gains and accuracy grades (B, C, Q). The CIDCKT designation indicates a specific gain variant in the SC-70-6 surface-mount package, designed for space-constrained applications requiring high precision.

Replacement Considerations

Check for INA210BIDCKT if higher accuracy is needed, or other gain variants within the INA210 family. Verify pin compatibility and electrical specifications before substituting.
