DS1620+ DIP-8 Temperaturgivare

Digital Thermometer and Thermostat

The DS1620 Digital Thermometer and Thermostat provides 9–bit temperature readings which indicate the temperature of the device. With three thermal alarm outputs, the DS1620 can also act as a thermostat. THIGH is driven high if the DS1620’s temperature is greater than or equal to a user–defined temperature TH. TLOW is driven high if the DS1620’s temperature is less than or equal to a user–defined temperature TL. TCOM is driven high when the temperature exceeds TH and stays high until the temperature falls below that of TL.

Features
