The TMP75 is a fully integrated digital temperature sensor that can work at low voltage (1.8V) and is fully pin and register compatible with NCT75 and ADT75. The TMP75 has a ±1°C accuracy over the operating temperature range. The on-chip 12-bit analog-to-digital converter (ADC) provides a temperature resolution of 0.0625°C. The TMP75 supports up to 8 devices address and provides an over-temperature alarm function. Based on programmable upper and lower temperature limits and an ALERT pin, the TMP75 can be used as a thermostat or an over-temperature alarm. The TMP75 has been precisely calibrated at the factory, and the user does not need to perform any additional processing on the temperature output.
