LM392P

Overview

The LM392P is a dual low-power operational amplifier and voltage comparator manufactured by Texas Instruments. It integrates two independent amplifiers and two comparators within a single 8-pin PDIP package. The device operates on a single supply voltage ranging from 3V to 32V, with a typical response time of 1.3μs. It features CMOS/TTL compatible outputs and draws a static current of approximately 500μA. The component supports an operating temperature range from 0°C to 70°C.

Feature Summary

• Integrates dual operational amplifiers and dual voltage comparators in one package
• CMOS and TTL logic level compatible output stages
• Low power consumption design suitable for battery applications
• Operates on wide single-supply voltage ranges

Applications

• Battery-powered equipment
• Voltage monitoring circuits
• Threshold detection systems
• Signal conditioning modules

Procurement Notes

Verify the specific suffix (e.g., NOPB) against the manufacturer's current datasheet to confirm lead-free compliance and RoHS status. Ensure the ordering code matches the exact PDIP-8 package variant required for your PCB footprint. Cross-reference the active lifecycle status directly with Texas Instruments to avoid obsolete part risks.

Selection Notes

Select this component when space constraints require combining both amplification and comparison functions. It is suitable for designs needing low quiescent current without sacrificing basic speed. Verify that the input common-mode voltage range meets your signal requirements relative to the ground rail.

Part Context

This part belongs to the LM392 family, which combines op-amp and comparator functionalities. It serves as a cost-effective solution for mixed-signal analog processing tasks where separate components would increase board area. The PDIP-8 package facilitates through-hole prototyping and assembly.

Replacement Considerations

Check for LM392N/NOPB or LM392M variants if different packaging styles are needed. Confirm pinout compatibility before substituting with other dual op-amp/comparator hybrids.
