Texas Instruments TMP102 Digital Temperature Sensor

Texas Instruments TMP102 Low-power, two-wire, serial output temperature sensor with an I²C/SMBus digital interface is ideal for NTC/PTC thermistor replacement where high accuracy is required. The sensor is highly linear and does not require complex calculations or lookup tables to derive the temperature. The Texas Instruments TMP102 is ideal for extended temperature measurement in a variety of communication, computer, consumer, environmental, industrial, and instrumentation applications.
