1.4 Device Information

The TMP4719 is a digital output temperature sensor with one local integrated sensor and two remote temperature sensor channels. This device communicates in a two-wire environment compatible with SMBus and I2C interfaces. The device can be set to make continuous or one-shot conversions, and additionally has alert functionalities using the ALERT and T_CRIT pins. The device is calibrated in production to achieve high accuracy, and is available in both VSSOP and WSON packages. The EVM includes a TMP4719DGSR (VSSOP) unit. For more information of the IC, please refer to the device data sheet. Table 1-3 includes some of the parameters of interest of the TMP4719 to consider when using this EVM.
