TI TMP116AIDRVR

The TMP116 family (TMP116, TMP116N) includes low-power, high-accuracy temperature sensors with integrated EEPROM memory. The TMP116 provides a 16-bit temperature result with a resolution of 0.0078°C and achieves accuracy up to ±0.2°C without calibration. The TMP116 is compatible with I²C and SMBus interfaces, features programmable alert functionality, and supports up to 4 devices on a single bus. The TMP116 not only conserves power but also draws minimal current, maximizing the reduction of self-heating and improving measurement accuracy. The TMP116 operates over a voltage range of 1.9V to 5.5V with a typical current consumption of 3.5μA. The TMP116 operates over a temperature range of -55°C to +125°C, offering higher accuracy than Class A RTDs while consuming less than one-fifth of the typical excitation current of a PT100 RTD. Compared to RTDs, the TMP116 is easier to use, requiring no calibration, external circuitry, matched traces, or Kelvin connections. TMP116 devices are fully tested during production, traceable through NIST, and verified using equipment calibrated to ISO/IEC 17025-certified standards.
