APPLICATION CIRCUITS
Figure 18 shows a typical application circuit for the ADM1021,
using a discrete sensor transistor connected via a shielded,
twisted pair cable. The pull-ups on SCLK, SDATA and
ALERT
are required only if they are not already provided elsewhere in
the system.
The SCLK, and SDATA pins of the ADM1021 can be inter-
faced directly to the SMBus of an I/O controller such as the
Intel PCI ISA IDE Xcelerator (PIIX4) chip type 82371AB.
Figure 19 shows how the ADM1021 might be integrated into a
system using this type of I/O controller.
