DESCRIPTION
The SM72375 is an ultra low power dual comparator
with a maximum 10 μA/comparator power supply
current. It is designed to operate over a wide range of
supply voltages, with a minimum supply voltage of
2.7V.
The common mode voltage range of the SM72375
exceeds both the positive and negative supply rails, a
significant advantage in single supply applications.
The open drain output of the SM72375 allows for
wired-OR configurations. The open drain output also
offers the advantage of allowing the output to be
pulled to any voltage rail up to 15V, regardless of the
supply voltage of the SM72375.
The SM72375 is targeted for systems where low
power consumption is the critical parameter. ensured
operation at supply voltages of 2.7V and rail-to-rail
performance makes this comparator ideal for battery-
powered applications.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
