The STDS75 is a high-precision CMOS (digital) temperature sensor IC with a delta-sigma analog-to-digital (ADC) converter and an I2C-compatible serial digital interface. It is targeted for general applications such as personal computers, system thermal management, electronics equipment, and industrial controllers, and is packaged in the industry-standard 8-lead TSSOP package.


The device contains a bandgap temperature sensor and programmable 9- to 12-bit ADC which monitor and digitize the temperature to a resolution up to 0.0625 °C. The STDS75 is typically accurate to (±3 °C - max) over the full temperature measurement range of –55 °C to 125 °C with ±2 °C accuracy in the –25 °C to +100 °C range. At power-up, the STDS75 defaults to 9-bit resolution for software compatibility with the STLM75.


The STDS75 is specified for operating at supply voltages from 2.7 V to 5.5 V. Operating at 3.3 V, the supply current is typically (125 μA).


The onboard delta-sigma analog-to-digital converter (ADC) converts the measured temperature to a digital value that is calibrated in °C; for Fahrenheit applications a lookup table or conversion routine is required.


The STDS75 is factory-calibrated and requires no external components to measure temperature.
