LMC6772/LMC6772Q Dual Micropower Rail-To-Rail Input CMOS Comparator
with Open Drain Output
January 8, 2010
LMC6772/LMC6772Q
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.

Note 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 guaranteed. For guaranteed specifications and the test conditions, see the electrical characteristics.
Note 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.
Note 3:
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.
Note 4:
The maximum power dissipation is a function of T
J(MAX)
, θ
JA
, and T
A
. The maximum allowable power dissipation at any ambient temperature is
P
D
= (T
J(MAX)
– T
A
)/θ
JA
. All numbers apply for packages soldered directly into a PC board.
Note 5:
Typical Values represent the most likely parametric norm.
Note 6:
All limits are guaranteed by testing or statistical analysis.
Note 7:
Do not short circuit output to V
+
, when V+ is > 12V or reliability will be adversely affected.
Note 8:
Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage ratings.
Note 9:
C
L
inlcudes the probe and jig capacitance. The rise time, fall time and propagation delays are measured with a 2V input step.
Note 10:
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.
