INA213BIDCKT

Overview

The INA213BIDCKT is a zero-drift current-shunt monitor manufactured by Texas Instruments. It features a fixed gain of 50 V/V and supports bidirectional high-side or low-side voltage output measurements. The device operates within a supply voltage range of 2.7 V to 26 V, with a maximum common-mode voltage of 12 V. Key electrical specifications include a gain error of 0.02%, an input bias current of 28 uA, and an input offset voltage of 1 uV. It functions as a single-channel amplifier with a gain-bandwidth product of 14 kHz and a typical operating supply current of 100 uA.

Feature Summary

• Zero-drift architecture ensures minimal offset voltage drift over temperature variations
• Supports both high-side and low-side bidirectional current sensing applications
• Provides precise measurement capabilities through a fixed internal gain of 50 V/V

Applications

• Battery management systems requiring accurate current monitoring
• Industrial process control loops for shunt-based current detection
• Power supply units utilizing high-side or low-side load sensing

Procurement Notes

Verify the specific suffix 'CKT' corresponds to the SC-70-6 package configuration when sourcing. Confirm RoHS compliance status directly from the manufacturer's latest documentation. Ensure the ordering part number matches the required gain and package type for your design implementation.

Selection Notes

Select this component for designs demanding high precision without external calibration due to its zero-drift technology. The fixed 50 V/V gain simplifies circuit design compared to programmable gain alternatives. Consider the 12 V common-mode limit when selecting for higher voltage bus monitoring applications.

Part Context

This device belongs to the INA21x series of current-shunt monitors, which are designed for high-precision measurement applications. The series utilizes chopper stabilization techniques to achieve ultra-low offset voltages and drift, making it suitable for sensitive analog signal conditioning tasks in industrial and automotive environments.

Replacement Considerations

The INA213BIDCKR serves as a reel-packaged alternative to the cut-tape CKT variant. Other members of the INA21x family may offer different gain values but share similar architectural characteristics.
