DESCRIPTION
The LMC6772 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 LMC6772
exceeds both the positive and negative supply rails, a
significant advantage in single supply applications.
The open drain output of the LMC6772 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 LMC6772.
The LMC6772 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 batterypowered
applications.
Refer to the LMC6762 datasheet for a push-pull
output stage version of this device.
