GENERAL DESCRIPTION

The ADCMP670 combine two low power, low voltage

comparators with a 400mV reference in the 6-lead TSOT

package. Operating within a supply range of 1.7V to 5.5V, the

devices only draw 6.5µA typical, making them ideal for low

voltage system monitoring and portable applications.

Hysteresis is included in the comparators to insure stable

output operation. Each comparator has only one input available

externally, the other inputs are connected internally to the

reference. The comparator outputs are open collector and the

output load can be referred to any voltage up to supply voltage.

The output stage sinking capability guaranteed greater than

5mA over temperature.

The ADCMP670 has one inverting input and one non-

inverting input, making it suitable for use as a window

comparator. Available in commercial, industrial and

automotive temperature ranges.
