Overview
The REF3112AQDBZRQ1 is an automotive-grade series voltage reference from Texas Instruments, delivering a fixed output of 1.25 V with an initial accuracy of ±0.2%. It operates within an input voltage range of 1.8 V to 5.5 V and consumes a maximum supply current of 135 µA. The device features a low temperature coefficient of 20 ppm/°C and supports a maximum shunt current of 10 mA. It functions reliably across an extended temperature range of -40°C to +125°C and holds AEC-Q100 qualification for automotive applications.
Feature Summary
- AEC-Q100 qualified for automotive reliability standards
- Low power consumption suitable for battery-operated systems
- High precision with tight initial accuracy and low drift
Applications
- Automotive sensor signal conditioning
- Data acquisition systems in vehicles
- Analog-to-digital converter references
Procurement Notes
Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification status. Ensure the SOT-23-3 package matches your PCB footprint requirements. Confirm that the 1.25 V output aligns with your system's reference needs. Check lead times as automotive parts may have longer production cycles than standard industrial components.
Selection Notes
Select this component when automotive certification is mandatory. Compare against REF3112AIDBZT if industrial grade suffices. Consider REF3312AIDBZR for lower quiescent current needs where higher drift is acceptable. Verify input voltage constraints do not exceed the 5.5 V maximum limit during transient conditions.
Part Context
This part belongs to the REF31xx family of precision voltage references. It shares core electrical characteristics with the REF3112AIDBZT but includes enhanced testing and documentation for automotive environments. The 'Q1' designation specifically indicates compliance with AEC-Q100 stress test qualifications required by major automotive manufacturers.
Replacement Considerations
REF3112AIDBZT serves as the non-automotive equivalent. REF3112AQDBZT is another automotive variant; verify if package or suffix differences impact compatibility. No direct pin-for-pin substitutes are confirmed in public data.
