INA215AIDCKT

Overview

The INA215AIDCKT is a high-side or low-side current shunt monitor manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 26 V and features a fixed gain of 75 V/V. The device provides a voltage output proportional to the sensed current. Key electrical parameters include a maximum common-mode voltage of 12 V, a gain-bandwidth product of 40 kHz, and an input bias current of 28 uA. It exhibits a typical input offset voltage of 1 uV and a common-mode rejection ratio of 140 dB. The component functions within a temperature range of -40 C to +125 C and consumes a maximum operating supply current of 100 uA.

Feature Summary

• Zero-drift architecture ensures low offset for accurate sensing with minimal shunt voltage drop
• Capable of measuring both high-side and low-side currents relative to the power supply
• High common-mode rejection ratio maintains accuracy across varying common-mode voltages

Applications

• Battery management systems
• Industrial process controls
• Power supply monitoring

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles during assembly. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when precise current measurement is required with minimal error due to offset voltage. The fixed 75 V/V gain suits applications where moderate amplification is sufficient without external resistors. Consider the 12 V common-mode limit; higher voltage applications may require alternative models within the series. Evaluate the 100 uA supply current against strict power budget constraints in portable designs.

Part Context

This device belongs to the INA21x family of zero-drift current shunt monitors. These components are designed to detect voltage drops across shunt resistors regardless of the common-mode voltage level. The family offers various gain options and packages, providing flexibility for different industrial and commercial sensing requirements while maintaining high accuracy over wide temperature ranges.
