DESCRIPTION
The
DS1626
and
DS1726
digital
thermometers/thermostats provide temperature
measurements and stand-alone thermostat
capability over a -55癈 to +125癈 range. The
DS1626 offers ?.5癈 accuracy from 0癈 to
+70癈 and the DS1726 has ?癈 accuracy from
-10癈 to +85癈. 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
overtemperature (T
H
) and undertemperature (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. Table 1
summarizes the user-accessible registers. Figure
1 shows a functional diagram.
