Overview
The ADM1032ARMZ-REEL is a dual-channel digital thermometer and under/overtemperature alarm produced by onsemi. It is designed for use in PCs and thermal management systems, capable of measuring the temperature of a remote thermal diode with an accuracy of ±1°C and its ambient temperature with an accuracy of ±3°C. The device is housed in an 8-pin MSOP package and communicates over a 2-wire serial interface compatible with SMBus standards. It features a novel measurement technique that cancels out the absolute value of the transistor’s base emitter voltage, eliminating the need for calibration. The ADM1032ARMZ-REEL is suitable for various applications including desktop and notebook computers, smart batteries, industrial controllers, telecommunications equipment, instrumentation, and embedded systems.
