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. |
