LMC7215/LMC7225
Micro-Power, Rail-to-Rail CMOS Comparators with
Open-Drain/Push-Pull Outputs and TinyPak™ Package
General Description
The LMC7215/LMC7225 are ultra low power comparators
with a maximum of 1 µA power supply current. They are de-
signed to operate over a wide range of supply voltages, from
2V to 8V.
The LMC7215/LMC7225 have a greater than rail-to-rail com-
mon mode voltage range. This is a real advantage in single
supply applications.
The LMC7215 features a push-pull output stage. This fea-
ture 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/LMC7225 are designed for systems where
low power consumption is the critical parameter.
Guaranteed operation over the full supply voltage range of
2.7V to 5V and rail-to-rail performance makes this compara-
tor ideal for battery-powered applications.
