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, of which three are dedicated to monitoring 5 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. Two further pins can be (continued on page 7 )
