N.C.
Combined Current Source and ADC Positive Input for Channel 2 Remote Diode. Connect DXP2 to
the anode of a remote-diode-connected, temperature-sensing transistor. Leave DXP2 unconnected
or connect to DXN2 if a remote diode is not used. Connect a 100pF capacitor between DXP2 and
DXN2 for noise filtering.
Cathode Input for Channel 2 Remote Diode. Connect the cathode of the channel 2 remote-diode-
connected transistor to DXN2. If the channel 2 remote transistor is a substrate pnp (e.g., on a CPU
die), connect the base of the pnp to DXN2. Leave DXN2 unconnected or connect to DXP2 if a
remote diode is not used. Connect a 100pF capacitor between DXP2 and DXN2 for noise filtering.
Combined Current Source and ADC Positive Input for Channel 3 Remote Diode. Connect DXP3 to
the anode of a remote-diode-connected, temperature-sensing transistor. Leave DXP3 unconnected
or connect to DXN3 if a remote diode is not used. Connect a 100pF capacitor between DXP3 and
DXN3 for noise filtering.
Cathode Input for Channel 3 Remote Diode. Connect the cathode of the channel 3 remote-diode-
connected transistor to DXN3. If the channel 3 remote transistor is a substrate pnp (e.g., on a CPU
die), connect the base of the pnp to DXN3. Leave DXN3 unconnected or connect to DXP3 if a
remote diode is not used. Connect a 100pF capacitor between DXP3 and DXN3 for noise filtering.
Combined Current Source and ADC Positive Input for Channel 4 Remote Diode. Connect DXP4 to
the anode of a remote-diode-connected, temperature-sensing transistor. Leave DXP4 unconnected
or connect to DXN4 if a remote diode is not used. Connect a 100pF capacitor between DXP4 and
DXN4 for noise filtering.
No Connection. Connect to other N.C. or leave unconnected.
