ADM1024ARU

Overview

The ADM1024ARU is a digital temperature sensor manufactured by Analog Devices Inc. It features an on-chip diode-connected PNP transistor for local temperature measurement and supports external remote sensors via a dedicated input. The device utilizes a two-wire serial interface compatible with SMBus standards for communication. It provides programmable overtemperature and undertemperature limits with an ALERT output signal when thresholds are exceeded. The component operates within a supply voltage range of 3 V to 5.5 V and is housed in a 16-lead QSOP package.
