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.
The DS1626 and DS1726 offer thermostatic functionality with three dedicated thermostat outputs (T
HIGH
,
T
LOW
, and T
COM
), and over-temperature (T
H
) and under-temperature (T
L
) user-programmable thresholds
stored in on-chip EEPROM. For stand-alone thermostat operation, T
H
and T
L
can be programmed prior to
installation, and the DS1626/DS1726 can be configured to automatically begin taking temperature
measurements at power-up.
Pin descriptions for the DS1626 and DS1726 are provided in Table 2 and user-accessible registers are
summarized in Table 3. A functional diagram is shown in Figure 1.
