DESCRIPTION

The DS1722 Digital Thermometer and Thermostat with SPI/3-Wire Interface provides temperature

readings which indicate the temperature of the device. No additional components are required; the device

is truly a temperature-to-digital converter. Temperature readings are communicated from the DS1722

over a Motorola SPI interface or a standard 3-wire serial interface. The choice of interface standard is

selectable by the user.

For applications that require greater temperature resolution, the user can adjust the readout resolution

from 8 to 12 bits. This is particularly useful in applications where thermal runaway conditions must be

detected quickly.

For application flexibility, the DS1722 features a wide analog supply rail of 2.65V - 5.5V. A separate

digital supply allows a range of 1.8V to 5.5V.

The DS1722 is available in an 8-pin SO (150mil) and 8-pin μMAX package.

Applications for the DS1722 include personal computers/servers/workstations, cellular telephones, office

equipment, or any thermally-sensitive system.
