LMV393DR2G

Overview

The LMV393DR2G is a dual-channel, general-purpose, low-voltage comparator manufactured by onsemi. It operates within a supply voltage range of 2.7 V to 5.0 V and features an input common-mode voltage range that extends to ground. The device utilizes an open-drain output stage suitable for wired-OR configurations. Key electrical characteristics include a typical propagation delay of 200 ns at 5 V, a maximum input offset voltage of 9 mV, and a quiescent current of 100 µA per channel at 5 V. It is housed in an SOIC-8 package.

Feature Summary

• Open-drain output configuration enables wired-OR logic applications
• Input common-mode voltage range includes ground potential
• Low quiescent current consumption optimized for portable devices
• Pb-Free and RoHS compliant construction

Applications

• Battery monitors
• Notebooks and PDAs
• General purpose portable devices
• General purpose low voltage applications

Procurement Notes

Verify the specific ordering suffix DR2G corresponds to the SOIC-8 package with tape and reel shipping quantities as defined in the official onsemi documentation. Confirm compliance requirements such as Pb-Free status and RoHS directives match project specifications before finalizing procurement orders.

Selection Notes

Select this component for designs requiring dual comparators in space-constrained environments operating from single low-voltage supplies. Ensure external pull-up resistors are included for the open-drain outputs. Consider thermal resistance limits when determining power dissipation capabilities within the specified ambient temperature range.

Part Context

This part belongs to the LMV3xx series, which represents low-voltage versions of industry-standard comparators. The series includes single (LMV331), dual (LMV393), and quad (LMV339) channel variants. These devices are designed to offer lower current consumption compared to predecessors while maintaining compatibility with standard logic levels.

Replacement Considerations

Cross-reference with other manufacturers' LMV393 equivalents or onsemi's NCV prefix automotive qualified versions if extended temperature ranges or specific site control requirements are necessary.
