LMV393X-VS1R

Overview

The LMV393X-VS1R is a dual low-power comparator manufactured by 3PEAK in an MSOP-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, internal hysteresis for clean switching, and an input common-mode range extending 0.1 V beyond the power rails. Key electrical parameters include a propagation delay of 120 ns (typical), an input offset voltage of ±4 mV, and an operating temperature range of -40°C to +125°C.

Feature Summary

• Internal hysteresis ensures clean switching and improved noise immunity
• Open-drain output allows flexible logic level shifting and wired-AND functionality
• Input common-mode range extends 0.1 V beyond the negative and positive supply rails
• No ESD diode between the output pin and the positive supply voltage

Applications

• Peak and Zero-Crossing Detectors
• Threshold Detectors/Discriminators
• Logic Level Shifting or Translation
• Window Comparators
• IR Receivers

Procurement Notes

Verify the specific suffix VS1R corresponds to the MSOP-8 package and standard commercial grade when ordering. Confirm that the required application environment falls within the specified -40°C to +125°C operating temperature range. Ensure the design accounts for the open-drain output requirement by including an appropriate external pull-up resistor connected to the desired logic voltage level.

Selection Notes

Select this component for applications requiring low power consumption and rail-to-rail input capability within a 2.5 V to 5.5 V supply range. The internal hysteresis makes it suitable for noisy environments without external components. Consider the MSOP-8 package for space-constrained designs. Note that the absence of an output-to-supply ESD diode enables independent pull-up voltages for level translation tasks.

Part Context

The LMV393X-VS1R belongs to the LMV393X series of general-purpose comparators designed for low-voltage operation. It serves as a low-power alternative to traditional comparators, offering high-speed performance with minimal current drain. The device is optimized for battery-operated portable consumer products and industrial sensing applications where space and power efficiency are critical constraints.

Replacement Considerations

LMV393X-VS1R-S is an automotive-grade qualified version of this part number.
