Dual Micropower Rail-To-Rail Input CMOS Comparator
with Open Drain Output
General Description
The LMC6772 is an ultra low power dual comparator with a
maximum 10 μA/comparator power supply current. It is de-
signed 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 ad-
vantage 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 con-
sumption is the critical parameter. Guaranteed operation at
supply voltages of 2.7V and rail-to-rail performance makes
this comparator ideal for battery-powered applications.
Refer to the LMC6762 datasheet for a push-pull output stage
version of this device.
