Digital local temperature sensor with I²C interface
The Texas Instruments TMP102AIDRLTG4 is a digital local temperature sensor that reports the die temperature over an I²C/SMBus interface with 12-bit resolution.
Accuracy and temperature range for system error budget
The 12-bit resolution provides 0.0625°C per LSB, which is fine enough for thermal management loops in portable or embedded systems without external filtering.
Supply voltage and power-saving features
Built-in features include One-Shot conversion mode, an open-drain output switch for alert signaling, and a Shutdown Mode that drops quiescent current to sub-microamp levels between readings.
The base product number TMP102 covers a family of I²C temperature sensors; the AIDRLTG4 suffix specifies the SOT-563 package and tape-and-reel delivery.
