Electromechanical Device Temperature DESCRIPTION
The TMP122 is an SPI-compatible temperature
sensor available in an SOT23-6 package. Requiring
only a pull-up resistor for complete function, the
TMP122 temperature sensor is capable of measuring
temperatures within 2В°C of accuracy over a
temperature range of -55В°C to 125В°C, with operation
up
to
150В°C. …
