Overview
The LM2903AVQDRQ1 is an automotive-grade dual differential voltage comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 32 V and draws a quiescent current between 1 mA and 2.5 mA. The device features a typical response time of 1.3 µs and supports open collector or open drain outputs. Input characteristics include a maximum input offset voltage of 4 mV and an input bias current of 250 nA. It is housed in an 8-SOIC surface-mount package and is qualified under AEC-Q100 standards for operation across temperatures from -40°C to +125°C.
Feature Summary
- Dual differential comparators designed for automotive applications
- Open collector and open drain output configurations
- Qualified to AEC-Q100 automotive reliability standards
Applications
- Automotive sensor signal conditioning
- Fire and carbon monoxide alarm detectors
- General purpose analog comparison circuits
Procurement Notes
Verify the specific suffix 'AVQDRQ1' against the manufacturer's official datasheet to confirm the exact temperature grade, package variant, and automotive qualification status. Ensure compatibility with the target PCB footprint for the SOIC-8 package. Confirm that the required input offset voltage and response time specifications meet the design constraints before finalizing procurement.
Selection Notes
Select this component when automotive reliability (AEC-Q100) is mandatory and low power consumption is required. The wide supply voltage range suits single-supply systems. Compare input offset voltage and bias current requirements against other variants in the LM2903-Q1 family if higher precision or different packaging options are needed for the specific application environment.
Part Context
This part belongs to the LM2903-Q1 series of dual differential comparators optimized for automotive electronics. It shares functional similarities with non-automotive LM2903 devices but includes enhanced testing and documentation to meet automotive industry quality and reliability standards. The 'AV' designation typically indicates specific performance grades within the automotive catalog line.
Replacement Considerations
LM2903AVQDRG4Q1 is listed as a related part number in distributor catalogs.
