ADVANCED INFORMATION

LMV331/ LM

393

GENERAL PURPOSE LOW VOLTAGE COMPARATOR

Description

The LMV331/LMV393 series are low voltage (2.7V to 5.5V) single

and dual comparators, which are designed to effectively reduce cost

and space at low voltage levels.

These devices offer specifications that meet or exceed the familiar

LM331/LM393 devices operating with a lower supply voltage and

consuming a far lower supply current.

The LMV331 is available in 5-Pin SOT353/SOT25 packages that

reduce space on PC boards and portable electronic devices. LMV393

is available in industry standard SOP-8 and MSOP-8 packages.

Features

• Guaranteed 2.7V and 5.5V performance

• Operating temperature range (-40°C to +125°C)

• Low supply current 40 µA/comparator Typ

• Input Common Mode Voltage Range includes ground

• Open Collector Output for Maximums Flexibility

• SOT353, SOT25, MSOP-8, SO-8: Available in “Green” Molding

Compound (No Br, Sb)

• Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)

• Halogen and Antimony Free. “Green” Device (Note 3)

Pin Assignments

Applications

• Mobile communications

• Battery powered devices

• Notebooks and PDA’s

• General purpose low voltage applications

• General purpose portable devices

Notes: 1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.

2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green"

and Lead-free.

3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and

<1000ppm antimony compounds.
