DS1721规格书详情
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 “temperature-to-digital” converter.
FEATURES
■ Temperature measurements require no external components with ±1°C accuracy
■ Measures temperatures from -55°C to +125°C; Fahrenheit equivalent is -67°F to +257°F
■ Temperature resolution is configurable from 9 to 12 (default) bits (0.5°C to 0.0625°C resolution)
■ Maximum conversion time (9-bit resolution) of 150 ms
■ Thermostatic settings are user-definable
■ Data is read/written via a 2-wire serial interface (open drain I/O lines); 3-bit addressability
■ Wide power supply range (2.7V - 5.5V)
■ Applications include personal computers, cellular telephones, office equipment, or any thermally sensitive system
■ 8-pin, 150-mil SOIC package and 8-pin µSOP package
