DESCRIPTION
The DS1626 and DS1726 digital thermometers/thermostats provide temperature measurements and stand-
alone thermostat capability over a -55°C to +125°C range. The DS1626 offers ±0.5°C accuracy from 0°C to
+70°C and the DS1726 has ±1°C accuracy from -10°C to +85°C. The resolution of the measured
temperature is user-selectable from 9 to 12 bits. Communication with the DS1626 and DS1726 is achieved
through a 3-wire serial bus.
