Overview
The LM2903VQDRQ1 is a dual differential voltage comparator from Texas Instruments, designed for automotive applications. It features an open-collector output and operates on single or dual power supplies ranging from 2V to 36V. The device provides two channels in an 8-pin SOIC package. Key electrical characteristics include a typical response time of 1.3µs, a maximum input offset voltage of 4mV at 5V, and a supply current between 600µA and 800µA. It functions within a temperature range of -40°C to +125°C.
Feature Summary
- Automotive-grade reliability certified under AEC-Q100 standards
- Dual-channel differential voltage comparison capability
- Open-collector output configuration for flexible interfacing
Applications
- Automotive sensor signal conditioning
- Voltage monitoring circuits
- Over-voltage protection systems
Procurement Notes
Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct automotive qualification and package type. Confirm that the specific revision matches project requirements. Cross-reference with authorized distributors to validate authenticity and traceability. Ensure compliance with RoHS directives as specified in the datasheet.
Selection Notes
Select this component when automotive certification is mandatory for dual comparator applications. Consider the 1.3µs propagation delay and 4mV offset voltage limits for precision requirements. Evaluate the 8-SOIC package dimensions for PCB layout constraints. Verify power supply compatibility within the 2V to 36V operational range.
Part Context
This device belongs to the LM2903-Q1 family of dual comparators. It shares functional similarities with other members like the LM2903BQDRQ1 but may differ in specific performance metrics such as offset voltage and speed. The 'V' suffix typically denotes a specific grade or variant within the automotive lineup.
Replacement Considerations
LM2903BQDRQ1 is a documented alternative within the same family. Verify if the performance differences in offset voltage and propagation delay meet application needs.
