LM393MX/NOPB

Overview

The LM393MX/NOPB is a dual analog comparator manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It operates on a single or split power supply ranging from 2 V to 36 V. The device features a typical response time of 700 ns and a maximum input offset voltage of 5 mV. Each channel provides a rail-to-rail output with a sink current capability of 16 mA. The operating supply current is typically 200 uA, with an input bias current of 250 nA. It functions within a temperature range of 0°C to +70°C.

Feature Summary

• Dual-channel differential comparison architecture
• Rail-to-rail output stage compatibility
• Low power consumption design
• RoHS compliant construction

Applications

• Over/under voltage detection circuits
• Temperature sensing systems
• Monitor circuit implementations

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout and electrical characteristics match the intended application requirements. Ensure the component source is authorized to guarantee authenticity and traceability. Cross-reference the datasheet revision date to validate parameter accuracy for production integration.

Selection Notes

Select this component when a dual-channel solution with low offset voltage and fast response is required in a compact surface-mount form factor. Consider the 16 mA output drive capability for direct interfacing with logic gates or indicator loads without additional buffering stages.

Part Context

This part belongs to the LM393 family of low-power comparators. It shares functional similarities with other variants like the LM393N but differs in packaging and mounting style. The NOPB suffix indicates lead-free and RoHS compliance, aligning with modern environmental standards for electronic components.
