NAME
FUNCTION
1
DXP1
Combined Current Source and A/D Positive Input for Channel 1 Remote Diode. Connect to the anode
of a remote-diode-connected temperature-sensing transistor. Leave floating or connect to DXN1 if no
remote diode is used. Place a 2200pF capacitor between DXP1 and DXN1 for noise filtering.
2
DXN1
Cathode Input for Channel 1 Remote Diode. Connect the cathode of the channel 1 remote-diode-
connected transistor to DXN1.
3
DXP2
Combined Current Source and A/D Positive Input for Channel 2 Remote Diode. Connect to the anode
of a remote-diode-connected temperature-sensing transistor. Leave floating or connect to DXN2 if no
remote diode is used. Place a 2200pF capacitor between DXP2 and DXN2 for noise filtering.
4
DXN2
Cathode Input for Channel 2 Remote Diode. Connect the cathode of the channel 2 remote-diode-
connected transistor to DXN2.
5
DXP3
Combined Current Source and A/D Positive Input for Channel 3 Remote Diode. Connect to the anode
of a remote-diode-connected temperature-sensing transistor. Leave floating or connect to DXN3 if no
remote diode is used. Place a 2200pF capacitor between DXP3 and DXN3 for noise filtering.
6
DXN3
Cathode Input for Channel 3 Remote Diode. Connect the cathode of the channel 1 remote-diode-
connected transistor to DXN3.
7
DXP4
Combined Current Source and A/D Positive Input for Channel 4 Remote Diode. Connect to the anode
of a remote-diode-connected temperature-sensing transistor. Leave floating or connect to DXN4 if no
remote diode is used. Place a 2200pF capacitor between DXP4 and DXN4 for noise filtering.
8
DXN4
Cathode Input for Channel 4 Remote Diode. Connect the cathode of the channel 1 remote-diode-
connected transistor to DXN4.
