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.
