Figure 7. ADuM3402 Pin Configuration
*
Pin 2 and Pin 8 are internally connected and connecting both to GND
1
is recommended. Pin 9 and Pin 15 are internally connected and
connecting both to GND
2
is recommended. In noisy environments, connecting output enables (Pin 7 for ADuM3401/ADuM3402 and
Pin 10 for all models) to an external logic high or low is recommended.
