APPLICATIONS Voltage detectors V CC Battery management systems ADCMP371 Analog-to-digital converters Low voltage applications IN+ Battery-powered electronics Portable equipment OUT GENERAL DESCRIPTION IN The ADCMP370/ADCMP371 are general-purpose comparators with input offset voltages of 9 mV (maximum) and low power GND consumption, which make them ideal for battery-powered, portable equipment. Figure 2. The ADCMP371 has a push-pull output stage, while the ADCMP370 has an open-drain output. The inputs on both parts and the output on the ADCMP370 can tolerate voltages up to 22 V, making them suitable for use as voltage detectors in portable equipment. The devices are available in space-efficient, 5-lead SC70 packaging. Rev. D Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
