INA212AIDCKR

Overview

The INA212AIDCKR is a single-channel, zero-drift current sense amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 26 V and features a maximum input offset voltage of 0.55 µV. The device draws a typical supply current of 65 µA and provides a slew rate of 0.4 V/µs with a gain-bandwidth product of 14 kHz. It utilizes an SC-70-6 surface-mount package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Zero-drift architecture ensures high precision by minimizing input offset voltage drift over temperature variations.

Applications

• Current sensing in battery-powered systems
• Low-side current monitoring in portable devices

Procurement Notes

Verify the specific suffix 'A' for accuracy grade and 'CKR' for the SC-70-6 tape-and-reel packaging configuration against official datasheets. Confirm that the Zero-Drift series specifications align with application requirements for low offset voltage and low supply current before finalizing procurement decisions.

Selection Notes

Select this component when ultra-low offset voltage and minimal drift are critical for measurement accuracy in space-constrained designs. The SC-70-6 package offers a compact footprint suitable for dense PCB layouts. Ensure the system operates within the specified 2.7 V to 26 V supply range and requires single-ended output capabilities.

Part Context

This part belongs to the INA210–INA215 family of zero-drift current sense amplifiers. These devices are designed for applications requiring high precision and low power consumption. The family shares similar architectural features but varies in accuracy grades and package options to suit different design constraints.

Replacement Considerations

Check for other members of the INA21x family with compatible packages and electrical characteristics. Verify pinout compatibility and ensure that alternative parts meet the same zero-drift performance and supply voltage requirements.
