Overview
The INA212AQDCKRQ1 is a zero-drift current sense amplifier manufactured by Texas Instruments, designed for automotive applications. It operates within a supply voltage range of 2.7 V to 26 V and features an SC-70-6 surface-mount package. The device supports a common-mode voltage from -0.3 V to 26 V and delivers a single-ended output. Key electrical specifications include a maximum input offset voltage of 5 µV, a gain bandwidth product of 4 kHz, and a slew rate of 0.4 V/µs. It draws a typical supply current of 65 µA and functions reliably across a temperature range of -40°C to 125°C.
Feature Summary
- Zero-drift architecture ensures high precision with low input offset voltage and minimal drift over temperature.
Applications
- Automotive battery monitoring systems
- Current sensing in electric vehicle powertrains
- High-side or low-side current measurement in automotive ECUs
Procurement Notes
Verify the AEC-Q100 qualification status and specific grade designation when sourcing. Confirm the SC-70-6 package marking and revision level against the latest TI datasheet. Ensure compatibility with automotive environmental standards required for your specific application zone.
Selection Notes
Select this component for applications requiring high accuracy in current sensing without external trimming. The zero-drift technology minimizes errors caused by temperature variations. Consider the 4 kHz bandwidth for slower response requirements. Verify that the SC-70-6 package fits your PCB layout constraints.
Part Context
This part belongs to the INA21xQ1 family of automotive-grade current sense amplifiers. It shares architectural similarities with other members like the INA213AQDCKRQ1 but offers specific gain and bandwidth characteristics tailored for general-purpose automotive current monitoring tasks.
Replacement Considerations
Check for direct pin-compatible alternatives within the INA21xQ1 series. Verify if higher bandwidth or different gain options are needed. Ensure any substitute maintains AEC-Q100 certification and SC-70-6 packaging.
