说明

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 battery-powered applications.

Refer to the LMC6762 datasheet for a push-pull output stage version of this device.
