Overview
The LM2903PWRG3 is a dual differential voltage comparator manufactured by Texas Instruments, belonging to the LMx93/LM2903 series. It features open-collector outputs and operates from a single power supply ranging from 2 V to 36 V. The device supports a common-mode input voltage range that includes ground. Key electrical parameters include a maximum input offset voltage of 7 mV, a typical response time of 1.5 µs, and a maximum operating temperature of +125 °C. It is housed in an 8-pin TSSOP package.
Feature Summary
- Dual differential input configuration for precise voltage comparison
- Open-collector output structure allowing flexible interfacing with various logic families
- Wide single-supply voltage operation capability
- Common-mode input range extends to ground potential
Applications
- General-purpose analog signal comparison
- Over-voltage and under-voltage monitoring circuits
- Window comparator designs
- Temperature sensing threshold detection
Procurement Notes
Verify the specific suffix 'G3' against official Texas Instruments documentation to confirm it denotes a lead-free or RoHS-compliant variant within the standard LM2903PWR family. Ensure the ordering part number matches the exact package type and temperature grade required for your design specifications before finalizing procurement.
Selection Notes
Select this component when a low-cost, general-purpose dual comparator with open-collector outputs is required. It is suitable for applications where the input voltage can reach ground level and where propagation delay around 1.5 µs is acceptable. Consider the TSSOP-8 package constraints for PCB layout and thermal management.
Part Context
This device is part of the widely used LMx93 series, which includes variants like LM193, LM293, and LM393. These comparators are designed for robust performance in single-supply environments. The LM2903 specifically offers industrial-grade temperature ranges and high input impedance characteristics compared to older bipolar counterparts.
Replacement Considerations
Direct pin-compatible substitutes include LM2903PWR, LM2903DR, and LM393 variants. For automotive applications, consider the LM2903-Q1 series. Verify that replacement parts maintain the same open-collector output topology and voltage ratings.
