The TMP75C is is a digital output temperature sensor capable of reading temperatures of -40ºC to +125ºC with 12 bits (0.0625 C) of resolution. The TMP75C uses a two-wire I2C protocol SMBus interface that allowsup to eight devices on one bus. It is ideal for extended temperature measurement in communication,computer, consumer, environmental, industrial, and instrumental applications. The TMP75CEVM is a platform for evaluating the performance of the TMP75 under various conditions. The TMP75CEVM consists of two PCBs. The first is the SM-USB-DIG board that communicates with the computer, provides power, and sends and receives appropriate digital signals. The second is the TMP75C test board, which contains the TMP75C and its support circuitry.
