Product Details

DESCRIPTION

The DS1721 2-Wire Digital Thermometer and Thermostat provides 12-bit temperature readings, which indicate the temperature of the device. Thermostatic settings and temperature readings are all communicated to/from the DS1721 over a simple 2-wire serial interface. No additional components are required; the device is truly a â€œtemperature-to-digitalâ€ converter.

FEATURES

â– Temperature measurements require no external components with Â±1Â°C accuracy
â– Measures temperatures from -55Â°C to +125Â°C; Fahrenheit equivalent is -67Â°F to +257Â°F
â– Temperature resolution is configurable from 9 to 12 (default) bits (0.5Â°C to 0.0625Â°C resolution)
â– Maximum conversion time (9-bit resolution) of 93.75 ms
â– Thermostatic settings are user-definable
â– Data is read/written via a 2-wire serial interface (open drain I/O lines); 3-bit addressability
â– Wide power supply range (2.7V - 5.5V)
â– Applications include personal computers, cellular telephones, office equipment, or any thermally sensitive system
â– 8-pin, 150-mil SOIC package and 8-pin ÂµSOP package
