INA210BIDCKR

Overview

The INA210BIDCKR is a single-channel, zero-drift current sense amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 26 V and supports bidirectional current sensing with both high-side and low-side monitoring capabilities. The device features a fixed gain of 200 V/V, a gain bandwidth product of 14 kHz, and a common-mode voltage rating of 12 V. Key electrical specifications include an input offset voltage of 550 nV, a common-mode rejection ratio of 140 dB, and a maximum gain error of 0.02%. It functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Zero-drift architecture ensures minimal input offset voltage drift over temperature variations
• Supports bidirectional current measurement for both high-side and low-side applications
• High precision performance with a fixed internal gain of 200 V/V

Applications

• Battery management systems
• Power supply current monitoring
• Industrial process control loops

Procurement Notes

Verify the specific suffix 'CKR' corresponds to the SC-70-6 package configuration when sourcing. Confirm that the component meets RoHS3 compliance standards required for your assembly line. Ensure proper handling procedures are followed due to moisture sensitivity classification. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity before procurement.

Selection Notes

Select this component when precise DC current measurement is required without external calibration. The fixed 200 V/V gain simplifies design by eliminating external resistors. Consider the 12 V common-mode limit to ensure compatibility with the target circuit's voltage levels. The SC-70-6 package offers space efficiency for compact board layouts.

Part Context

This device belongs to the INA210 series of current shunt monitors. It shares architectural similarities with other members like the INA212 and INA214 but differs in specific gain settings and bandwidth characteristics. The series is designed for general-purpose current sensing applications requiring high accuracy and low power consumption.

Replacement Considerations

INA210AIDCKR: Same series member with potentially different initial accuracy grades.
