DESCRIPTION
The LMC6762 is an ultra low power dual comparator
with a maximum supply current of 10 μA/comparator.
It is designed to operate over a wide range of supply
voltages, from 2.7V to 15V. The LMC6762 has
ensured specifications at 2.7V to meet the demands
of 3V digital systems.
The LMC6762 has an input common-mode voltage
range which exceeds both supplies. This is a
significant advantage in low-voltage applications. The
LMC6762 also features a push-pull output that allows
direct connections to logic devices without a pull-up
resistor.
A quiescent power consumption of 50 μW/amplifier
(@ V+ = 5V) makes the LMC6762 ideal for
applications in portable phones and hand-held
electronics. The ultra-low supply current is also
independent of power supply voltage. Ensured
operation at 2.7V and a rail-to-rail performance
makes this device ideal for battery-powered
applications.
Refer to the LMC6772 datasheet for an open-drain
version of this device.

(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) If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.
(3) Human body model, 1.5 kΩ in series with 100 pF.
(4) Do not short circuit output to V+, when V+ is greater than 12V or reliability will be adversely affected.
(5) 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.
(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.
