Overview
The ADT7310TRZ is a high-accuracy digital temperature sensor produced by Analog Devices Inc. It is housed in a narrow SOIC package and features a band gap temperature reference along with a 13-bit Analog-to-Digital Converter (ADC) to monitor and digitize temperature readings. This sensor is designed to provide precise temperature measurements without the need for user calibration or linearity correction, making it suitable for a wide range of applications.
