See Table 2 for Pin Descriptions.
General Description
The DS1631, DS1631A, and DS1731 digital thermome-
ters provide 9, 10, 11, or 12-bit temperature readings over
a -55°C to +125°C range. The DS1631 and DS1631A
thermometer accuracy is ±0.5°C from 0°C to +70°C with
3.0V ≤ V
DD
≤ 5.5V, and the DS1731 accuracy is ±1°C
from -10°C to +85°C with 3.0V ≤ V
DD
≤ 5.5V. The ther-
mostat on all three devices provides custom hysteresis
with user-defined trip points (T
H
and T
L
). The T
H
and
T
L
registers and thermometer configuration settings are
stored in NV EEPROM so they can be programmed prior
to installation. In addition, the DS1631A automatically
begins taking temperature measurements at power-up,
which allows it to function as a stand-alone thermostat.
Pin descriptions for the DS1631/DS1631A/DS1731 are pro-
vided in Table 2 and user-accessible registers are summa-
rized in Table 3. A functional diagram is shown in Figure 1.
