pin may also be used to monitor an analog temperature sensor such
as the LM60, since readings from this input can be routed to the fan
control logic.

reading. This pin may also be used to monitor an analog
temperature sensor such as the LM60, since readings from this
input can be routed to the fan control logic.
This input selects the lower two bits of the LM94 SMBus slave
address.

DD
power input for LM94. Generally this is connected to +3.3V
standby power.
The LM94 can be powered by +3.3V if monitoring in low power
states is not required, but power should be applied to this input
before any other pins.
This pin also serves as the analog input to monitor the 3.3V
stand-by (SB) voltage. It is necessary to bypass this pin with a 0.1
μF in parallel with 100 pF. A bulk capacitance of 10 μF should be in
the near vicinity. The 100 pF should be closest to the power pin.
Digital Ground. Digital ground and analog ground need to be tied
together at the chip then both taken to a low noise system ground.
A voltage difference between analog and digital ground may cause
erroneous results.
