INA210AIDCKRG4

Overview

The INA210AIDCKRG4 is a zero-drift current sense amplifier manufactured by Texas Instruments. It features a single-channel, single-ended output architecture housed in an SC-70-6 package. The device operates within a supply voltage range of 2.7 V to 26 V and supports a common-mode voltage range from -300 mV to 26 V. Key electrical characteristics include a maximum input offset voltage of 0.55 µV, a typical supply current of 65 µA, and a gain-bandwidth product of 14 kHz. It provides a minimum common-mode rejection ratio (CMRR) of 100 dB and maintains operation across a temperature range of -40°C to +125°C.

Feature Summary

• Zero-drift architecture ensures high precision with minimal offset voltage drift over temperature variations.
• Wide common-mode voltage range allows accurate current sensing across various system power rails.
• Low quiescent current consumption supports battery-powered and energy-efficient applications.

Applications

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

Procurement Notes

Verify the specific suffix 'RG4' corresponds to the reel packaging configuration as defined by Texas Instruments documentation. Confirm that the component meets RoHS3 compliance requirements for your manufacturing process. Ensure the SC-70-6 footprint matches your PCB layout guidelines. Cross-reference the datasheet revision to confirm thermal and electrical specifications align with your design constraints before finalizing procurement.

Selection Notes

Select this component when ultra-low offset voltage and low drift are critical for measurement accuracy. The wide common-mode range makes it suitable for high-side or low-side sensing in systems with varying supply voltages. Consider the SC-70-6 package size if board space is limited. Verify that the 14 kHz bandwidth is sufficient for the signal frequencies present in your application environment.

Part Context

This part belongs to the INA210 series of current sense amplifiers from Texas Instruments. The series is characterized by its zero-drift technology, which eliminates the need for external trimming. The INA210 family offers various gain options and package configurations to accommodate different design requirements while maintaining high precision in current monitoring applications.

Replacement Considerations

Consult official Texas Instruments substitution guides for verified alternatives. Generic equivalents may not match the zero-drift performance or specific common-mode voltage ranges. Verify pin compatibility and electrical parameters against the original datasheet before implementation.
