PRODUCT DESCRIPTION
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 V
CC
. One input (two pins) is dedicated to a
remote temperature-sensing diode. Two further pins can be
