Analog Devices ADT7302 Micropower Digital Temperature Sensor Product Handbook
The ADT7302 is a complete temperature monitoring system offered in space‑saving SOT‑23 and MSOP packages. It integrates a band‑gap temperature sensor with a 13‑bit ADC, delivering ±2 °C accuracy and a resolution of 0.03125 °C. The device features a low‑power standby mode and a flexible serial interface compatible with SPI, QSPI, MICROWIRE, and DSP protocols.
The handbook details electrical specifications, pin‑out diagrams, timing diagrams, mounting recommendations, and ordering information. It also includes typical performance curves, absolute maximum ratings, and guidelines for supply decoupling and thermal mounting, helping designers integrate the sensor into medical, automotive, industrial, and consumer applications.
