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 noninverting input, making it suitable for use as a window ...
