LM393DMR2

Overview

The LM393DMR2G is a dual independent precision voltage comparator manufactured by onsemi, housed in an 8-pin Micro8 package. It supports single supply operation from 2.0 Vdc to 36 Vdc and split supplies of ±1.0 Vdc to ±18 Vdc. The device features a very low current drain of 0.4 mA, low input bias current of 25 nA, and low input offset voltage of 5.0 mV maximum. It includes ESD clamps on inputs for increased ruggedness.

Feature Summary

• Dual independent comparators with wide single-supply range capability
• Low power consumption with current drain independent of supply voltage
• Input common-mode voltage range extends to ground level
• Outputs compatible with DTL, ECL, TTL, MOS, and CMOS logic levels

Applications

• Consumer electronics signal processing
• Automotive sensing applications
• Industrial control systems

Procurement Notes

Verify the specific suffix 'MR2' corresponds to the Micro8 package and tape & reel shipping configuration as defined in the official ordering information. Confirm RoHS compliance and Pb-Free status requirements against project specifications before finalizing procurement orders.

Selection Notes

Select this component when a compact Micro8 footprint is required for dual comparator functions. Ensure the application operates within the specified temperature range and utilizes open-collector outputs with appropriate pull-up resistors for the target logic family compatibility.

Part Context

This part belongs to the LM393 series of low offset voltage dual comparators. It shares functional characteristics with variants such as LM393DR2G (SOIC-8) and LM2903, differing primarily in package type and operating temperature ranges. The DM suffix indicates the Micro8 case style.

Replacement Considerations

LM393DR2G offers identical electrical performance in an SOIC-8 package. LM2903 provides extended industrial temperature capabilities. Verify pinout compatibility and thermal dissipation requirements when substituting packages.
