FEATURES
DESCRIPTION
The LMC7215/LMC7215-Q1/LMC7225 are ultra low
power comparators with a maximum of 1 μA power
supply current. They are designed to operate over a
wide range of supply voltages, from 2V to 8V.

Ultra Low Power Consumption 0.7 μA
Wide Range of Supply Voltages 2V to 8V
Input Common-Mode Range Beyond V+ and V−
Open Collector and Push-Pull Output
The LMC7215/LMC7215-Q1/LMC7225 have
a
greater than rail-to-rail common mode voltage range.
This is a real advantage in single supply applications.
High Output Current Drive: (@ VS = 5V) 45 mA
The LMC7215 features a push-pull output stage. This
feature allows operation with absolute minimum
amount of power consumption when driving any load.
Propagation Delay (@ VS = 5V, 10 mV
Overdrive) 25 μs

Tiny 5-Pin SOT-23 Package
The LMC7225 features an open drain output. By
connecting an external resistor, the output of the
comparator can be used as a level shifter to any
desired voltage to as high as 15V.
Latch-up Resistance >300 mA
LMC7215-Q1 is an Automotive Grade Product
that is AEC-Q100 Grade 3 Qualified.
The LMC7215/LMC7215-Q1/LMC7225 are designed
for systems where low power consumption is the
critical parameter.
