LMC6762  Product Folder

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 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. 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.
