LMV393MM

Overview

The LMV393MM is a dual general-purpose analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5 V and features an open collector/open drain output type. The device exhibits a typical response time of 450 ns and consumes 140 uA of operating power. Key electrical parameters include a maximum input offset voltage (Vos) of 7 mV, an input bias current (Ib) of 250 nA, and an input offset current (Ios) of 50 nA. It is housed in a VSSOP-8 package and supports surface mount installation.

Feature Summary

• Dual-channel configuration for compact circuit integration
• Low-voltage operation capability down to 2.7 V
• Open collector/drain output structure for flexible interfacing

Applications

• Low-voltage signal processing circuits
• Battery-powered monitoring systems
• General-purpose threshold detection

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS standards. Confirm the VSSOP-8 package dimensions match the design footprint. Ensure the 2.7 V to 5 V supply range aligns with the target application's power constraints. Check for any specific temperature grade requirements beyond the standard commercial range.

Selection Notes

Select this component when space-saving VSSOP-8 packaging is required alongside low-voltage operation. Compare propagation delay specifications against other variants if faster switching is needed. Consider the open-drain output requirement for pull-up resistor implementation in the final schematic design.

Part Context

This part belongs to the LMV3xx series, which are low-voltage versions of industry-standard comparators. The series is designed for applications where space saving is a constraint due to tiny packages. It serves as a modern alternative to older bipolar comparators with reduced current consumption.

Replacement Considerations

LMV393MMX/NOPB is a reel-pack variant of the same device.
