The TMP175 is a high-accuracy, low-power, NTC / PTC thermistor replacement digital temperature sensor for temperature measurement in communications,computer,consumer,environmental, industrial,  and instrumentation applications.The TMP175 provides  ≤ ±0.5°C temperature accuracy over the normal  operating range of -40°C to +125°C with good  temperature linearity. 

The rated operating voltage range of the TMP175 is 1.4V ~ 5.5V, and the quiescent current in actual temperature conversion is less than 40μA. The on-chip analog-to-digital converter (ADC) provides a temperature resolution of 0.0625°C. The TMP175 is available in an LM75-compatible 8-Pin MSOP / SOP package that supports SMBus and I 2C interfaces. Up to 27.

TMP175 device addresses or 8 TMP175 device addresses can be mounted on one bus. The TMP175 provides SMBus Alert function.
