LM2903SNG

Overview

The LM2903SNG is a dual analog comparator manufactured by onsemi, housed in an SOIC-8 surface-mount package. It operates within a supply voltage range of 2 V to 36 V and supports extended industrial temperatures from -40°C to +105°C. Key electrical specifications include a typical response time of 1.5 µs, a maximum input offset voltage of 7 mV, and an input bias current of 250 nA. The device features open-collector outputs capable of sourcing up to 16 mA per channel while consuming approximately 1 mA of quiescent current.

Feature Summary

• Dual-channel architecture with open-collector outputs compatible with various logic families
• Extended temperature operation suitable for industrial environments
• Wide single-supply voltage capability including negative rail input common-mode range

Applications

• Industrial process control signal monitoring
• Over-voltage and under-voltage protection circuits
• Temperature sensing threshold detection

Procurement Notes

Verify the specific suffix 'SNG' against official manufacturer documentation to confirm pinout and thermal characteristics. Confirm RoHS compliance status through the latest datasheet revision. Check availability as distribution channels may vary for this specific package variant.

Selection Notes

Select this component when dual comparators are required in a compact SOIC-8 footprint. Ensure the 1.5 µs response time meets system speed requirements. Verify that the open-collector output configuration aligns with the downstream logic interface needs.

Part Context

This part belongs to the LM2903V series of low-power dual comparers. It shares core electrical performance with other variants in the family but differs in packaging and temperature rating specifications defined by the manufacturer's product line structure.

Replacement Considerations

Cross-reference with LM2903VDG or LM2903DR2G for functional equivalents. Verify package compatibility and temperature range alignment before substitution.
