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 unconnected or connect to V

CC

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.

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 unconnected or connect to V

CC

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 unconnected or connect to V

CC

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.

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 unconnected or connect to V

CC

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 4 remote-diode-
connected transistor to DXN4.
