Overview
The LM2903VQDRG4 is a dual differential voltage comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 36 V (single) or ±1 V to ±18 V (dual). The device features an open-drain output type and supports surface-mount installation in an 8-SOIC package. Key electrical parameters include a maximum input offset voltage of 7 mV at 32 V, a typical quiescent current of 2.5 mA, and a maximum input bias current of 0.25 µA at 5 V. It functions across an extended temperature range from -40°C to +125°C.
Feature Summary
- Dual differential architecture for precise signal comparison
- Open-drain outputs compatible with CMOS and TTL logic families
- Wide single-supply operating voltage range up to 36 V
Applications
- General-purpose analog signal processing
- Temperature sensing circuits
- Voltage level detection systems
Procurement Notes
Verify the specific suffix G4 indicates lead-free and RoHS compliance status against the manufacturer's latest documentation. Confirm the SOIC-8 package dimensions and pinout match the design requirements. Ensure the automotive or industrial grade designation aligns with the intended operational environment specifications.
Selection Notes
Select this component when a dual comparator with wide supply voltage tolerance is required. The open-drain output facilitates wired-OR configurations. Consider the 7 mV input offset voltage limit for precision applications. Verify thermal performance within the -40°C to +125°C range for the specific enclosure design.
Part Context
This part belongs to the LM2903V series of dual differential comparators. It shares functional similarities with the LM193, LM293, and LM393 families but offers specific voltage and temperature characteristics defined by the 'V' and 'G4' suffixes. It serves as a standard solution for basic comparison tasks in mixed-signal designs.
Replacement Considerations
LM2903QDRG4 is a documented similar part number within the same family offering comparable dual differential comparator functionality.
