Overview
The ADM1032ARMZ-2RL7, produced by onsemi, is a dual-channel digital thermometer designed for monitoring both local and remote system temperatures. It is particularly suited for use in PCs and thermal management systems. The device can accurately measure the temperature of a remote thermal diode, such as those found on processor dies or discrete devices, with a precision of ±1°C. Additionally, it measures its ambient temperature. The ADM1032 communicates via a 2-wire serial interface compatible with System Management Bus (SMBus) standards, allowing for the programming of under/overtemperature limits and the generation of alerts when these limits are exceeded.
