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.

version of this device.
