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.
