Overview
The INA212AIDCKTG4 is a single-channel, bidirectional current shunt monitor manufactured by Texas Instruments. It features a zero-drift architecture with an input offset voltage of 0.55 µV and a supply current of 65 µA. The device operates on a single supply voltage ranging from 2.7 V to 26 V and supports a common-mode voltage range of -0.3 V to 26 V. It provides a fixed gain of 20 V/V and utilizes a SC-70-6 surface-mount package. The component is rated for operation between -40°C and +125°C.
Feature Summary
- Zero-drift architecture ensures low offset voltage for accurate sensing at small shunt voltages
- Bidirectional capability allows detection of current flow in both directions across the shunt resistor
- Wide common-mode voltage range enables monitoring independent of the system power supply level
Applications
- Battery management systems requiring precise current monitoring
- Overcurrent protection circuits in industrial equipment
- Load switch control applications
Procurement Notes
Verify the complete part number including the G4 suffix to ensure compliance with RoHS standards and lead-free manufacturing requirements. Confirm that the SC-70-6 package dimensions align with your PCB footprint constraints. Check for any recent Product Change Notifications regarding assembly sites or material updates before finalizing procurement.
Selection Notes
Select this component when high precision is required at low voltage drops across the shunt resistor due to its zero-drift technology. Ensure the application voltage does not exceed the 26 V maximum limit. Consider the 65 µA supply current for power-sensitive designs. Verify that the fixed 20 V/V gain meets the signal conditioning requirements of the downstream analog-to-digital converter or microcontroller.
Part Context
This device belongs to the INA21x family of current shunt monitors from Texas Instruments. The family offers various gain options and packaging styles to suit different space and accuracy requirements. The INA212 specifically targets applications needing high accuracy with minimal external calibration.
Replacement Considerations
The INA212AIDCKR is a pin-compatible alternative within the same series. Verify if the reel versus cut-tape packaging difference impacts your assembly process.
