Figure 14. Application Circuit
APPLICAT ION CIRCUIT
Figure 14 shows a generic application circuit using the
AD9240. T he analog monitoring inputs are connected to the
power supplies including two processor core voltage inputs. T he
VID inputs are connected to the processor voltage ID pins.
T here are two tacho inputs from fans, and the analog output is
used to control the speed of a third fan. A chassis intrusion
latch with an opto-sensor is connected to the CI input. Of
course, in an actual application, every input and output may not
be used, in which case unused analog and digital inputs should
be tied to analog or digital ground as appropriate.
