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

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but specific performance is not ensured. For ensured specifications and the test
conditions, see the electrical characteristics.
(2) Human body model, 1.5 kΩ in series with 100 pF. The output pins of the two comparators (pin 1 and pin 7) have an ESD tolerance of
1.5 kV. All other pins have an ESD tolerance of 2 kV.
(3) Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage ratings.
(4) Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in
exceeding the maximum allowed junction temperature of 150°C. Output currents in excess of ±30 mA over long term may adversely
affect reliability.
(5) Do not short circuit output to V+, when V+ is > 12V or reliability will be adversely affected.
(6) The maximum power dissipation is a function of TJ(MAX), θJA, and TA. The maximum allowable power dissipation at any ambient
temperature is PD = (TJ(MAX) – TA)/θJA. All numbers apply for packages soldered directly into a PC board.

(1) Typical Values represent the most likely parametric norm.
(2) All limits are specified by testing or statistical analysis.
(3) Input offset voltage Average Drift is calculated by dividing the accelerated operating life drift average by the equivalent operational time.
The input offset voltage average drift represents the input offset voltage change at worst-case input conditions.
