INA210BIDCKT

Overview

The INA210BIDCKT is a single-channel, bidirectional current-shunt monitor from the Texas Instruments INA21x series. It features a fixed gain of 200 V/V and operates within a supply voltage range of 2.7 V to 26 V. The device supports both low-side and high-side measurements with a common-mode voltage capability of 12 V. Key electrical specifications include a maximum input offset voltage of 550 nV, an input bias current of 28 uA, and a gain error of 0.02%. It offers a gain-bandwidth product of 14 kHz and a common-mode rejection ratio of 140 dB. The component functions at a quiescent current of 100 uA and is rated for operation between -40°C and +125°C.

Feature Summary

• Provides zero-drift performance with ultra-low input offset voltage and drift characteristics for high-precision sensing.
• Supports bidirectional current measurement in both low-side and high-side configurations.
• Delivers high common-mode rejection ratio to maintain accuracy in noisy environments.

Applications

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

Procurement Notes

Verify the specific suffix 'CKT' corresponds to the SC-70-6 package and tape-and-reel quantity when ordering. Confirm that the bidirectional functionality aligns with system requirements for negative current detection. Ensure the 12 V common-mode limit is sufficient for the target application's shunt placement. Check humidity sensitivity handling procedures during storage and assembly.

Selection Notes

Select this component when a fixed 200 V/V gain is appropriate for the expected shunt voltage range. Consider the 14 kHz bandwidth if higher frequency response is not required. Compare against the INA214 variant if a lower gain of 100 V/V or lower offset voltage is needed. Verify that the SC-70-6 package fits the available PCB footprint constraints.

Part Context

This part belongs to the INA21x family of zero-drift current-shunt monitors. It shares architectural similarities with the INA214 but differs in fixed gain settings. The series is designed for applications demanding high DC accuracy without external calibration. It complements other Texas Instruments amplifiers by offering integrated signal conditioning for shunt-based current measurement.

Replacement Considerations

The INA214BIDCKT serves as a functional alternative within the same package, offering a different fixed gain of 100 V/V. Verify that the change in gain does not require adjustments to the downstream ADC reference or scaling circuitry. Both parts share similar power and temperature specifications.
