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_Hand T_Lcan 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.
