STDS75 is a digital temperature sensor and thermal watchdog from ST company, with wide measurement range (-55 °C to +125 °C), high accuracy (+/-0.5 °C), low operating current (125 µA) and support I2C/SMBus interface.
The STDS75 is a high-precision CMOS digital temperature sensor IC with a delta-sigma analog-to-digital converter and an I2C-compatible serial digital interface. It is designed for general applications such as personal computers, system thermal management, and industrial controllers. The device is packaged in an industry-standard 8-lead TSSOP package and requires no external components to measure temperature.
