The EMC1414 supports reading two external diodes on the same set of pins (DP2, DN2). These
diodes are connected as shown in
diodes will be reverse biased by a V
only discrete thermal diodes (such as a 2N3904) are recommended to be placed on these pins.
The EMC1413/EMC1414 can be configured to measure a CPU substrate transistor, a discrete 2N3904
thermal diode, or an AMD processor diode on the External Diode 1 channel only. For the EMC1414
the External Diode 2 and External Diode 3 channels are configured to measure a pair of discrete anti-
parallel diodes (shared on pins DP2 and DN2). The supported configurations for the external diode
channels are shown in
