INA210AIDCKTG4

Overview

The INA210AIDCKTG4 is a single-channel, bi-directional current shunt monitor from Texas Instruments' Zero-Drift series. It features a fixed gain of 200 V/V and operates on a supply voltage range of 2.7 V to 26 V. Key electrical parameters include a maximum input offset voltage of 550 nV, an input bias current of 28 µA, and a common-mode rejection ratio of 140 dB. The device supports a common-mode voltage up to 12 V and has a gain-bandwidth product of 14 kHz. It functions within an operating temperature range of -40°C to +125°C and is housed in a SC-70-6 surface-mount package.

Feature Summary

• Bi-directional measurement capability for high-side or low-side current sensing applications
• Zero-drift architecture ensuring ultra-low input offset voltage and minimal drift over temperature
• High common-mode rejection ratio for accurate signal processing in noisy environments

Applications

• Battery management systems requiring precise current monitoring
• Industrial process control loops with shunt-based current feedback
• Overcurrent protection circuits in power distribution units

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and lead-free status as per Texas Instruments documentation. Confirm the SC-70-6 package type matches design constraints. Ensure the fixed 200 V/V gain aligns with system requirements before procurement. Check for any obsolescence notices or lifecycle changes directly from the manufacturer.

Selection Notes

Select this component when high precision is required without external calibration due to its zero-drift technology. The fixed 200 V/V gain simplifies circuit design by eliminating external resistors. Consider the 12 V common-mode limit and 26 V supply range against system voltages. The SC-70-6 package is suitable for space-constrained PCB layouts.

Part Context

This part belongs to the INA210 family of current shunt monitors, which are designed for high-accuracy current sensing. The family utilizes chopper-stabilized amplifiers to achieve near-zero drift characteristics. The INA210AIDCKTG4 specifically denotes the A-grade version with enhanced accuracy specifications compared to standard grades.

Replacement Considerations

Direct substitutes within the same family include the INA210AIDCKT. Verify pin compatibility and gain settings when replacing. Other Zero-Drift current monitors from Texas Instruments may serve as alternatives if gain or package differences are acceptable.
