Analog Devices ADT7320 Digital SPI Temperature Sensor Datasheet
The ADT7320 is a high‑precision digital temperature sensor in a 4 mm × 4 mm LFCSP package. It integrates a band‑gap reference, temperature sensor and a 16‑bit ADC, providing a resolution of 0.0078 °C. It operates from 2.7 V to 5.5 V, with typical supply current of 210 µA at 3.3 V and a shutdown current of 2 µA.
The device features programmable over‑temperature and under‑temperature thresholds with open‑drain CT and INT pins that can work in comparator or interrupt mode. Communication is via a standard SPI interface, and the sensor is suited for industrial, instrumentation and medical applications where accuracy and low power are critical. This manual is written in Chinese.
