ADT75 is a ±1°C accurate 12-bit digital temperature sensor with SMBus/I2C compatible interface, operating temperature range from -55°C to +125°C, operating voltage range from 3V to 5.5V.
The ADT75 is a complete temperature monitoring system available in 8‑lead MSOP and SOIC packages. It integrates a band‑gap temperature sensor with a 12‑bit ADC, providing a resolution of 0.0625 °C and features such as shutdown mode and an OS/ALERT open‑drain output.
Designed for a wide range of applications—including isolated sensors, environmental control, computer thermal monitoring, industrial process control, and hand‑held devices—the device operates from –55 °C to +125 °C and from 3 V to 5.5 V supply voltage. Up to eight ADT75 devices can share a single SMBus/I²C bus.
