The LTC®2983 is a high precision digital temperature measurement system that integrates all of the necessary
components to excite, calibrate, measure and digitize diodes, thermistors, thermocouples and RTDs. An SPI interface
provides readout of temperature in °C and simple configuration of many convenient features, including automatic
cold junction compensation, linearization coefficients, fault detection, and dual excitation current sources with
automatic mismatch compensation, current reversal and current ranging.
