INA213AIDCKRG4

Overview

The INA213AIDCKRG4 is a bidirectional, zero-drift current-shunt monitor featuring a voltage output. It operates with a single supply voltage ranging from 2.7V to 26V and supports common-mode voltages from -0.3V to 26V. The device offers a fixed gain of 200 V/V, resulting in a maximum full-scale differential input of 50mV. Key electrical specifications include a maximum input offset voltage of 5µV, a typical gain error of 0.1%, and a power supply current of 100µA maximum. It functions within an extended temperature range of -40°C to +125°C.

Feature Summary

• Zero-drift architecture ensures low offset voltage for high-precision measurements across the operating temperature range.
• Bidirectional sensing capability allows detection of current flow in both directions relative to ground.
• Supports both high-side and low-side current monitoring configurations without requiring level shifting.

Applications

• Battery management systems
• Overcurrent protection circuits
• Load switch control

Procurement Notes

Verify the G4 suffix indicates lead-free packaging and RoHS compliance as per Texas Instruments standards. Confirm the SC-70 package dimensions match your PCB footprint requirements. Ensure the fixed gain selection aligns with your expected shunt voltage levels to avoid saturation or insufficient resolution.

Selection Notes

Select this component when high accuracy is required over a wide temperature range due to its zero-drift characteristics. The fixed 200 V/V gain suits applications with small shunt resistors. Consider the 26V common-mode limit for higher voltage bus monitoring. The SC-70 package is suitable for space-constrained designs.

Part Context

This part belongs to the INA21x series of current-shunt monitors from Texas Instruments. The series is characterized by zero-drift technology and bidirectional operation. The INA213 variant specifically provides a fixed gain of 200 V/V, distinguishing it from other members of the family that may offer different gain options or channel counts.

Replacement Considerations

INA213AIDCKR is the non-RoHS equivalent. INA213BQDCKRQ1G4 is an automotive-grade alternative with AEC-Q100 qualification.
