LMV393S-13

Overview

The LMV393S-13 is a dual general-purpose low-voltage comparator manufactured by Diodes Incorporated. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and features an open-collector output structure. The device includes two independent comparators within an SO-8 package, with input common-mode voltage ranges extending to ground. Electrical characteristics include a typical supply current of 40 µA per comparator at 2.7 V and up to 100 µA at 5 V. Propagation delays vary between 200 ns and 600 ns depending on input overdrive conditions.

Feature Summary

• Dual-channel architecture providing two independent comparators in a compact surface-mount package
• Open-collector output configuration allowing flexible interfacing with various logic families
• Input common-mode voltage range extends to ground, enabling direct sensing of signals near the negative rail
• Operates across a wide industrial temperature range from -40°C to +125°C

Applications

• Mobile communications equipment
• Battery-powered portable devices
• Notebooks and personal digital assistants (PDAs)
• General-purpose low-voltage signal conditioning

Procurement Notes

Verify that the ordering suffix '-13' corresponds to the specified tape and reel packaging quantity of 2,500 units. Confirm the package code 'S' matches the required SO-8 footprint for PCB layout compatibility. Ensure the component meets RoHS and halogen-free requirements as defined by the manufacturer's green product standards before finalizing procurement specifications.

Selection Notes

Select this component when a dual comparator solution is required for space-constrained portable designs. The open-collector output necessitates an external pull-up resistor, typically between 1 kΩ and 10 kΩ, to function correctly. Consider the propagation delay variations under different load capacitances and input overdrive voltages when designing high-speed signal paths.

Part Context

This part belongs to the LMV331/LMV393 series, which are low-voltage counterparts to the industry-standard LM331 and LM393 comparators. The series utilizes a BiCMOS process to achieve improved noise performance while consuming significantly less power than older bipolar technologies. The LMV393 specifically provides dual channels, whereas the LMV331 offers a single channel.
