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.
■ Temperature Measurements Require No External Components ■ Measures Temperatures from -55°C to +120°C. Fahrenheit Equivalent is -67°F to +248°F ■ Thermometer Accuracy is ±2.0°C ■ Thermometer Resolution is Configurable from 8 to 12 bits (1.0°C to 0.0625°C Resolution) ■ Data is Read From/Written to Via a Motorola Serial Peripheral Interface (SPI) or Standard 3-Wire Serial Interface ■ Wide Analog Power Supply Range (2.65V - 5.5V) ■ Separate Digital Supply Allows for 1.8V Logic ■ Available in an 8-Pin SO (150mil) and 8-Pin μMAX package S |
