Product Introduction

Overview

The ADM1032ARMZ-002, produced by onsemi, is a dual-channel digital thermometer designed for thermal management in various electronic systems, particularly in desktop and notebook computers. This device is capable of measuring both local and remote temperatures with high accuracy. It features a novel measurement technique that eliminates the need for calibration by canceling out the absolute value of the transistor’s base-emitter voltage. The ADM1032 communicates via a 2-wire serial interface compatible with System Management Bus (SMBus) standards, allowing for programmable under/overtemperature limits and alerts.
