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 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.
