LMV393X-SO1R

Overview

The LMV393X-SO1R is a dual low-power voltage comparator from 3PEAK, housed in an SOP-8 package. It operates on a single supply voltage ranging from 2.5 V to 5.5 V with a quiescent current of 50 μA per channel. The device features an open-drain output and includes internal hysteresis for noise immunity. Input common-mode voltage extends 100 mV beyond the rails, and it lacks ESD diodes between inputs/output and the positive supply. Operating temperature range is -40°C to +125°C.

Feature Summary

• Low power consumption suitable for battery operation
• Internal hysteresis ensures clean switching
• Open-drain output allows flexible logic interfacing
• Input common-mode range extends beyond supply rails

Applications

• Peak and Zero-Crossing Detectors
• Threshold Detectors/Discriminators
• Sensing at the Ground or Supply Line
• Logic Level Shifting or Translation
• IR Receivers

Procurement Notes

Verify the specific suffix 'SO1R' corresponds to the SOP-8 package and standard commercial grade specifications. Confirm that the automotive qualified variants (ending in '-S') are not required if AEC-Q100 reliability testing is not needed for the application. Ensure pull-up resistor values align with the open-drain output requirements for the target logic levels.

Selection Notes

Select this component when low supply current and rail-to-rail input capability are critical within a 5.5 V maximum limit. The absence of input ESD diodes to the positive supply enables level shifting applications where the output pull-up can exceed the supply voltage. Verify that the open-drain output configuration meets the system's drive requirements.

Part Context

This part belongs to the LMV331X/LMV393X series of general-purpose comparators designed for low-voltage applications. The series offers single, dual, and quad configurations in various small packages including SOT23-5, SC70-5, MSOP8, and SOP8. These devices are optimized for portable consumer products requiring space-saving solutions and extended operating temperatures.
