APPLICATIONS Battery-Powered System Monitoring Threshold Detectors Relay Driving Optoisolator Driving Industrial Control Systems Handheld Instruments GENERAL DESCRIPTION The ADCMP361 is a single low power, low voltage comparator with a 400mV reference in the 5-lead SOT-23 package. Operating within a supply range of 1.7V to 5.5V, the device only draw 6.5A typical, making it ideal for low voltage system monitoring and portable applications. Hysteresis is included in the comparators to insure stable output operation. The comparator has only one input available externally, the other input is connected internally to the reference. The comparator has both an inverting and a noninverting output. The output stage sinking capability guaranteed greater than 5mA over temperature. Available in commercial, industrial and automotive temperature ranges. Rev. PrB Information furnished by Analog Devices is believed to be accurate and reliable.

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 10 of 13 Preliminary Technical Data APPLICATIONS INFORMATION The ADCMP361 is a low power comparator 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. ADCMP361 COMPARATORS AND INTERNAL REFERENCE The comparators has one input available externally and the other input is 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. OUTPUTS The ADCMP361 has both inverting and noninverting outputs available to provide a more flexible solution in applications where the user may need to utilize the comparator in either inverting or noninverting modes.
