INA210AIDCKR

Overview

The INA210AIDCKR is a single-channel current sense amplifier from Texas Instruments, featuring a zero-drift architecture for high precision. It operates within a supply voltage range of 2.7 V to 26 V and supports bidirectional current sensing with an input common-mode voltage up to 12 V. The device provides a fixed gain of 200 V/V and achieves a maximum gain error of 0.02%. Key electrical specifications include a 14 kHz gain-bandwidth product, 140 dB common-mode rejection ratio, and a quiescent current of 65 µA. It functions reliably across an extended temperature range of -40°C to +125°C.

Feature Summary

• Zero-drift technology ensures minimal offset voltage drift over time and temperature variations.
• Bidirectional sensing capability allows accurate measurement of current flow in both directions.
• High common-mode rejection ratio maintains signal integrity in noisy environments.

Applications

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

Procurement Notes

Verify the specific suffix 'CKR' corresponds to the SC-70-6 package and tape-and-reel quantity configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly line. Ensure the ordering part number matches the exact gain and accuracy grade specified in your design documentation before finalizing procurement.

Selection Notes

Select this component when high DC accuracy is critical due to its zero-drift characteristics. The fixed 200 V/V gain suits applications where shunt voltages are small. Consider the SC-70-6 package size constraints and the 12 V common-mode limit against your system's rail voltages and shunt placement.

Part Context

This device belongs to the INA210 family of current shunt monitors. It shares architectural similarities with other members like the INA212 and INA214 but offers a specific fixed gain of 200 V/V. The family is designed for low-power, high-precision applications in portable and industrial electronics.

Replacement Considerations

The INA210BIDCKR is a direct functional substitute within the same series, offering identical performance metrics and pinout compatibility. Verify that the B-grade accuracy meets your specific tolerance requirements if substituting.
