LMC6762 Dual MicroPower Rail-To-Rail Input CMOS Comparator with Push-Pull Output
July 1997
LMC6762
Dual MicroPower Rail-To-Rail Input CMOS Comparator
with Push-Pull Output
General 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 guaranteed specs 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 de-
vices 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.
Guaranteed 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.
