DS1626, DS1726 pdf datasheet (

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.
The DS1626 and DS1726 offer thermostatic
functionality with three dedicated thermostat
outputs (THIGH, TLOW, and TCOM), and
overtemperature (TH) and undertemperature (TL)
user-programmable thresholds stored in on-chip
EEPROM. For stand-alone thermostat operation,
TH and TL can be programmed prior to
installation, and the DS1626/DS1726 can be
configured to automatically begin taking
temperature measurements at power-up. Table 1
summarizes the user-accessible registers. Figure
1 shows a functional diagram.
