LM393APG4

Overview

The LM393APG4 is a dual differential analog comparator manufactured by Texas Instruments, belonging to the LM393A series. It features an open-collector output compatible with CMOS and TTL logic families. The device operates within a supply voltage range of 4 V to 30 V and consumes 2.5 mA of operating current. Key electrical specifications include a maximum input offset voltage of 2 mV and an input bias current of 250 nA. It provides a response time of 1.3 µs and functions reliably across a temperature range of 0°C to +70°C.

Feature Summary

• Dual differential configuration for precise signal comparison
• Open-collector output ensures compatibility with various logic standards
• Wide single-supply voltage operation capability

Applications

• Over-voltage detection circuits
• Window comparator designs
• Temperature sensing interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for End-of-Life notices, as availability may be limited. Ensure packaging matches project requirements, typically tube format for this package type. Validate datasheet revisions against specific design constraints before final procurement decisions.

Selection Notes

Select this component when high precision is required due to its low 2 mV offset voltage specification compared to standard variants. The PDIP-8 through-hole package facilitates prototyping and manual assembly processes. Consider the 250 nA input bias current for high-impedance sensor applications where leakage currents must remain minimal during operation.

Part Context

This part belongs to the LM393 family of dual comparators, widely used in industrial and consumer electronics. The 'A' suffix denotes tighter performance tolerances, specifically regarding offset voltage and bias current. The 'P' indicates a plastic dual-in-line package, while 'G4' signifies lead-free manufacturing compliant with environmental directives.

Replacement Considerations

LM393ADR serves as a surface-mount alternative within the same series. LM393APSR offers identical electrical characteristics in a tape-and-reel format for automated assembly. Verify pinout compatibility and thermal management requirements when substituting packages.
