Description

SERMODE CE SCLK GND VDDA SDO SDI VDDD - Serial Interface Mode - Chip Enable - Serial Clock - Ground - Analog Supply Voltage - Serial Data Out - Serial Data In - Digital Supply Voltage 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

Features

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 SOIC (150 mil).
