Overview
The LM2903Q2T is a dual low-power voltage comparator from STMicroelectronics, designed for operation with single or split power supplies. It features a wide supply voltage range of 2 V to 36 V and includes an input common-mode range that encompasses the negative rail. The device offers low quiescent current, high output drive capability up to 16 mA, and outputs compatible with various logic families including TTL, CMOS, and ECL. Packaged in an 8-DFN format, it supports surface-mount installation.
Feature Summary
- Dual independent comparators optimized for low-power consumption across wide voltage ranges
- Input common-mode voltage range extends to the negative supply rail
- Outputs are compatible with TTL, DTL, ECL, MOS, and CMOS logic families
- Automotive-grade qualification compliant with AEC-Q100 standards
Applications
- Automotive sensor signal conditioning circuits
- General-purpose voltage monitoring systems
- Logic interface circuits between analog sensors and digital processors
Procurement Notes
Verify the specific suffix Q2T against the official STMicroelectronics datasheet to confirm package type and automotive grade status. Ensure the ordering code matches the required reel or cut tape configuration. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.
Selection Notes
Select this component when dual comparators with automotive reliability are required. It is suitable for designs needing wide supply voltage tolerance and low static current. Consider the 8-DFN package constraints for thermal management and PCB layout. Verify that the input offset voltage and response time meet the specific application requirements.
Part Context
This device belongs to the LM2903 series, which consists of dual low-power voltage comparators. The 'Q' designation indicates automotive qualification under AEC-Q100 standards. The '2T' suffix typically denotes the specific packaging configuration, such as tape and reel, intended for automated surface-mount assembly processes.
