The TMP102A is a digital temperature sensor with high-accuracy, low-power, and NTC/PTC thermistor replacements. It can be used for extended temperature measurement in communication, computer, consumer electronics, environmental, industrial and instrumentation applications. The TMP102A provides ≤ ± 0.5°C temperature accuracy with good temperature linearity over the normal operating range of -40°C to +125°C. The TMP102A can provide extended temperature measurement mode, extending the temperature measurement range from -55°C to +150°C.

The rated working voltage range of the TMP102A is 1.4V~5.5V, and the maximum quiescent current in the entire working rage is 10µA (temperature measurement frequency 4Hz). The on-chip 12-bit ADC offers resolutions down to 0.0625°C.

The TMP102A adopts SOT563 / DFNWB package of 1.6mm × 1.6mm, is compatible with SMBus and I2C interface, and allows up to four devices on one bus. The device also features an SMBus alert function.
