System Hardware Monitor with Remote Diode Thermal Sensing

The ADM1024 is a complete system hardware monitor for microprocessor-based systems, providing measurement and limit comparison of various system parameters. Eight measurement inputs are provided; three are dedicated to monitoring 5.0 V and 12 V power supplies and the processor core voltage. The ADM1024 can monitor a fourth power supply voltage by measuring its own VCC. One input (two pins) is dedicated to a remote temperature-sensing diode.
