The STTS22H is a compact, high-accuracy digital temperature sensor designed for reliable thermal monitoring across a wide operating range. It integrates a bandgap sensor, ADC, and signal processing with an I²C/SMBus 3.0 interface in a tiny UDFN-6 package. Factory calibrated and NIST traceable, it delivers precise temperature readings without additional calibration.
With ultra-low power consumption as low as 1.75 µA in one-shot mode, it is ideal for battery-powered applications. The device supports programmable thresholds, interrupt output, and multiple I²C addresses, enabling flexible system integration. Its 16-bit output ensures fine resolution, while user-selectable operating modes help optimize performance and power. Designed for modern electronics, it offers dependable and accurate sensing in compact and portable devices.
