LM2903AVQPWRG4

Overview

The LM2903AVQPWRG4 is a dual differential voltage comparator from Texas Instruments, designed for single-supply operation. It features an open-collector output type and operates within a supply voltage range of 2 V to 32 V. The device has a typical response time of 1.3 µs and a maximum operating temperature of +125 °C. It is housed in a TSSOP-8 package with two channels.

Feature Summary

• Dual differential input configuration for precise voltage comparison
• Open-collector output structure allowing flexible interfacing
• Wide single-supply voltage capability for diverse power environments

Applications

• Over-voltage detection circuits
• Window comparator designs
• Level shifting applications

Procurement Notes

Verify the specific suffix G4 indicates lead-free status and RoHS compliance as per manufacturer specifications. Confirm the TSSOP-8 package dimensions match your PCB footprint requirements. Ensure the open-collector output logic aligns with your downstream circuit pull-up resistor needs.

Selection Notes

Select this component when a dual-channel solution is required for single-supply systems. The wide input common-mode range including ground makes it suitable for low-side sensing. Consider the 1.3 µs propagation delay for timing-sensitive applications where faster comparators are not mandatory.

Part Context

This part belongs to the LM2903 family of analog comparators. It shares functional similarities with other members like the LM2903AVQDR but differs in package type and specific electrical tolerances. The G4 suffix typically denotes environmental compliance enhancements over earlier revisions.

Replacement Considerations

LM2903AVQDR offers similar functionality in an SOIC-8 package. LM2903PWRG4 provides comparable performance in a TSSOP-8 package but may have different offset voltage characteristics.
