FEATURES
Requires no external components
Supply voltage range covers from 2.7V to
5.5V
Measures temperatures from –55°C to
+125°C in 0.5°C increments. Fahrenheit
equivalent is –67°F to +257°F in 0.9°F
increments
Temperature is read as a 9–bit value
Converts temperature to digital word in 1
second (max)
Thermostatic settings are user–definable and
non–volatile
Data is read from/written via a 3–wire serial
interface (CLK, DQ,
RST
)
Applications include thermostatic controls,
industrial systems, consumer products,
thermometers, or any thermally sensitive
system

DESCRIPTION
The DS1720 Digital Thermometer and Thermostat provides 9–bit temperature readings which indicate
the temperature of the device. With three thermal alarm out-puts, the DS1720 can also act as a thermostat.
T
HIGH
is driven high if the DS1720’s temperature is greater than or equal to a user–defined temperature
T
H
. T
LOW
is driven high if the DS1720’s temperature is less than or equal to a user–defined temperature
T
L
. T
COM
is driven high when the temperature exceeds T
H
and stays high until the temperature falls below
that of TL.
User–defined temperature settings are stored in non–volatile memory, so parts can be programmed prior
to insertion in a system, as well as used in stand–alone applications without a CPU. Temperature settings
and temperature readings are all communicated to/from the DS1720 over a simple 3–wire interface.
