NAME
FUNCTION
Combined Current Source and A/D Positive Input for Channel 1 Remote Diode. Connect to the anode
1
DXP1 of a remote-diode-connected temperature-sensing transistor. Leave unconnected or connect to VCC 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. Internally connected to GND.
Combined Current Source and A/D Positive Input for Channel 2 Remote Diode. Connect to the anode
3
DXP2 of a remote-diode-connected temperature-sensing transistor. Leave unconnected or connect to VCC 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.
Combined Current Source and A/D Positive Input for Channel 3 Remote Diode. Connect to the anode
5
DXP3 of a remote-diode-connected temperature-sensing transistor. Leave unconnected or connect to VCC 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 3 remote-diode-
connected transistor to DXN3.
