STTS75 main features

The STTS75 is a high-precision CMOS digital temperature sensor IC with a programmable

9- to 12-bit analog-to-digital (ADC) converter and an I2C-compatible serial digital interface..

The STTS75 typically accuracy is ±3 °C over the full temperature measurement range of

–55 to 125 °C, and ±2°C in the –25 to 100°C range.

It operates from a 2.7 to 5.5 V supply voltage, with a typical supply current of 75 µA at 3.3 V.

For the demonstration datalogger application, the sensor is configured to the default

resolution settings that is 9 bits, to achieve a temperature resolution of 0.5 °C.

The STTS75 is factory-calibrated and requires no external components to measure

temperature.
