- Additional features for improved temperature measurement accuracy:
- Diode non-ideality factor (η-factor) correction
- Series resistance cancellation
- Programmable digital filter
- Remote diode fault detection
- 1.2V logic-compatible input thresholds independent of supply
- Footprint compatible with the TMP432
The TMP4719 device is a high-accuracy 0.8°C temperature sensor with one local integrated sensor and two remote temperature sensor channels that can be connected to diode-connected transistors, such as the popular MMBT3904 NPN transistor, to replace traditional thermistors or thermocouples. The remote channels can also be connected to a substrate thermal transistor or diode integrated inside microprocessors, microcontrollers, or FPGAs to monitor the die temperature of the IC.
The TMP4719 supports series resistance cancellation, programmable ideality factor (η-factor), configurable temperature limits, and programmable digital filters to improve the noise immunity and provide a robust design for complex thermal environment monitoring applications. The device supports I2C and SMBus communication with logic levels down to 1.2V regardless of the main supply rail, enabling interoperability with low-voltage MCUs without needing a secondary low-voltage supply or a bus level shifter.
