TMP75B Evaluation Module
Texas Instruments TMP75B Digital Output Temperature Sensor Evaluation Module is a platform for evaluating the performance of the TMP75 under various conditions. The TMP75B is a digital output temperature sensor capable of reading temperatures of -40ºC to +125ºC with 12-bits (0.0625 C) of resolution. The TMP75B uses a two-wire I2C protocol SMBus interface that allows up to eight devices on one bus. The TMP75BEVM consists of two PCBs. The first communicates with the computer, provides power, and sends and receives appropriate digital signals. The second is the TMP75B test board, which contains the TMP75B and its support circuitry.
