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.
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.
The LMC7215 features a push-pull output stage. This
feature allows operation with absolute minimum
amount of power consumption when driving any load.
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.
The LMC7215/LMC7215-Q1/LMC7225 are designed
for systems where low power consumption is the
critical parameter.
Ensured operation over the full supply voltage range
of 2.7V to 5V and rail-to-rail performance makes this
comparator ideal for battery-powered applications.
