Product Introduction

Overview

The ADT7302ARMZ is a highly accurate, micropower digital temperature sensor produced by Analog Devices Inc. This component is designed to provide precise temperature measurements and is available in compact SOT-23 and MSOP packages. It integrates a band gap temperature sensor and a 13-bit analog-to-digital converter (ADC), enabling it to monitor and digitize temperature readings with a high resolution of 0.03125°C. The device operates over a wide temperature range of −40°C to +125°C and features a flexible serial interface compatible with SPI, QSPI, and MICROWIRE protocols, as well as DSPs.
