Overview
The LMV393M/NOPB 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 consumes 140 uA of operating power. The device features an open collector and open drain output type with a response time of 450 ns. Input offset voltage is specified at 7 mV, while input bias current is 250 nA. It functions in temperatures from -40 C to +85 C and is housed in an SOIC-8 package.
Feature Summary
- Dual-channel low-voltage operation suitable for space-constrained designs
- Open collector and open drain outputs for flexible interfacing
- General-purpose performance with low current consumption
Applications
- Low voltage signal processing circuits
- Battery-powered monitoring systems
- Threshold detection applications
Procurement Notes
Verify the specific suffix NOPB indicates lead-free compliance and RoHS status. Confirm the SOIC-8 package dimensions match the design footprint requirements. Ensure the operating temperature range of -40 C to +85 C aligns with the target environment specifications before finalizing procurement.
Selection Notes
Select this component when a dual comparator is required for low-voltage single-supply applications. The LMV393M/NOPB offers a balance of speed and power efficiency. Consider the open-drain output requirement for pull-up resistor implementation. Verify that the 450 ns propagation delay meets the system timing constraints.
Part Context
This part belongs to the LMV393 series, which are low-voltage versions of industry-standard comparators. The series is designed for applications where power conservation and small form factors are critical. The LMV393M/NOPB variant specifically utilizes the SOIC-8 surface-mount package for automated assembly compatibility.
Replacement Considerations
LMV393MMX/NOPB is a reel-packaged alternative within the same family. LMV393ID is a discontinued industrial-grade variant in SOIC-8. Verify pinout compatibility and electrical parameter overlaps before substituting.
