Product Overview
The TMP102 is a Texas Instruments digital temperature sensor in the Sensor category. It is specified for a 1.4-3.6 V recommended supply range, with 3.3 V nominal operation, and covers -40 to 125 °C for both operating free-air temperature and temperature sensing range. Accuracy is specified as ±0.5 °C typical and ±2 °C maximum from -25 °C to 85 °C, and ±1 °C typical and ±3 °C maximum across -40 °C to 125 °C.
The device uses an SMBus, two-wire, I2C-compatible digital interface. Address selection through ADD0 allows up to four devices on one bus. SDA and ALERT are open-drain outputs requiring pullup resistors, with ALERT used as an overtemperature output. Conversion rates include 0.25, 1, 4, and 8 conversions per second, with 4 conversions per second as the default setting.
The TMP102 is assembled in a SOT563 (DRL) 6-pin package measuring 1.60 mm x 1.60 mm nominal. Package-related thermal data includes 240.2 °C/W junction-to-ambient thermal resistance and 96.4 °C/W junction-to-case top thermal resistance. These facts support use in compact, low-voltage temperature measurement, SMBus/I2C sensor nodes, multi-device temperature monitoring, and overtemperature alert applications.
