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.
