Micro-Power / Rail-to-Rail CMOS Comparators with Open-Drain/Push-Pull Outputs and TinyPak Package
LMC7215/LMC7225
Micro-Power, Rail-to-Rail CMOS Comparators with
Open-Drain/Push-Pull Outputs and TinyPak™ Package
General DescriptionThe LMC7215/LMC7225are ultralow power comparators
witha maximumof1 μApower supply current. Theyarede-
signed tooperate overa wide range ofsupplyvoltages, fromto8V.
The LMC7215/LMC7225havea greater than rail-to-rail com-
mon mode voltage range. Thisisareal advantagein single
supply applications.
The LMC7215 featuresa push-pull output stage. This fea-
ture allows operation with absolute minimum amountof
power consumption when drivingany load.
The LMC7225 featuresan open drain output.By connecting external resistor,the outputofthe comparator canbe
usedasa level shiftertoany desired voltagetoas highas
15V.
The LMC7215/LMC7225are designedfor systems where
low power consumptionisthe critical parameter.
Guaranteed operation overthefull supply voltage rangeof
2.7Vto5Vand rail-to-rail performance makesthis compara-
tor idealfor battery-powered applications.
Features(Typical unless otherwise noted) Ultralow power consumption0.7μA Wide rangeof supply voltages2Vto8V Input common-mode range beyondV+andV− Open collectorand push-pull output High output current drive:(@VS=5V)45mA Propagation delay(@VS=5V,10mV overdrive)25μs Tiny SOT23-5 package Latch-up resistance >300mA
