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 6.5A 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 comparator. Available in commercial, industrial and automotive temperature ranges. Rev.

This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Rev.

PrB | Page 11 of 14 ADCMP670 APPLICATIONS INFORMATION The ADCMP670 is a dual low power comparators with a build in 400mV reference that operates from 1.7V to 5.5V. The comparators are approx 0.8% accurate with a built in hysteresis of approx 6.5mV. The outputs are open drain capable of sinking 40mA Preliminary Technical Data COMPARATORS AND INTERNAL REFERENCE Each of the comparators has one input available externally, comparator A has a noninverting input and comparator B has an inverting input available. The other comparator inputs are connected internally to the 400mV reference. The rising input threshold voltage of the comparators is designed to be equal to that of the reference (i.e.400mV). ADDING HYSTERESIS To prevent oscillations at the output caused by noise or slowly moving signals passing the switching threshold, each comparator has built-in hysteresis of approximately 6.5mV. Positive feedback can be used to adjust hysteresis to the noninverting comparators. Rev.
