Operating Instructions Digital Thermometer and Thermostat Demonstration Kit DS1620
|
FEATURES ♦ Requires no external components
♦ Supply voltage range covers from 2.7V to 5.5V ♦ Measures temperatures from -55°C to +125°C in 0.5°C increments; Fahrenheit equivalent is -67°F to +257°F in 0.9°F increments
♦ Temperature is read as a 9-bit value ♦ Converts temperature to digital word in 1 second (max) ♦ Thermostatic settings are user-definable and nonvolatile ♦ Data is read from/written via a 3-wire serial interface (CLK, DQ, RST ) ♦ Applications include thermostatic controls, industrial systems, consumer products, thermometers, or any thermally sensitive system ♦ 8-pin DIP or SOIC (208-mil) packages
PIN DESCRIPTION DQ - 3-Wire Input/Output CLK/ CONV - 3-Wire Clock Input and Stand-alone Convert Input RST - 3-Wire Reset Input GND - Ground THIGH - High Temperature Trigger TLOW - Low Temperature Trigger TCOM - High/Low Combination Trigger VDD - Power Supply Voltage (3V - 5V)
