Low-Voltage, ±0.5°C Accuracy Digital Thermometer and Thermostat www.maxim-ic.com DS620 GENERAL DESCRIPTION The DS620 digital thermometer and thermostat provides low-voltage (1.7V £ VDD £ 3.5V) temperature measurements with ±0.5°C accuracy from 0°C to +70°C and an operating temperature range of -55°C to +125°C. The DS620 communicates over a 2-wire digital interface. For distributed-sensing applications, it is multidroppable with three address pins that allow up to eight DS620s to operate on a single bus. The DS620 has thermostat functionality with userdefined thresholds stored in EEPROM registers, and it can be configured for standalone thermostat operation.
