LINEAR TECHNOLOGY LTC2983 high performance digital temperature measurement 
integrates all necessary components to excite, calibrate, measure and digitize diodes, thermistors, thermocouples and RTDs with 0.1°C conformity. Device provides multiplexed high precision interface to virtually any sensor. An SPI interface provides readout of temperature in °C and simple configuration of many convenient features. Device builds on firm’s LTC2983 by adding EEPROM (electrically erasable programmable read-only memory) that stores user configuration data and custom sensor coefficients. This addition eliminates any IC or sensor programming by a host processor and facilitates the use of self-contained temperature sensing boards or modules. http://www.linear.com
