Figure 4. ADuM1300 Pin Configuration
Figure 5. ADuM1301 Pin Configuration
* Pins 2 and 8 are internally connected. Connecting both to GND
1
is recommended. Pins 9 and 15 are internally connected. Connecting both to GND
2
is recommended.
Output enable Pin 10 on the ADuM1300 may be left disconnected if outputs are to be always enabled. Output enable Pins 7 and 10 on the ADuM1301 may be left
disconnected if outputs are to be always enabled. In noisy environments, connecting Pin 7 (for ADuM1301) and Pin 10 (for both models) to an external logic high or
low is recommended.
