Pin No.
OUTA
OUTB
Note 7: DDX® and Binary Full-Bridge outputs are bridged. The output OUTA produces signals in phase
with the input. The output OUTB produces signals out of phase with the input.
Note 8: Half-Bridge Binary Mode outputs are NOT bridged. All outputs produce signals in phase with the
respective inputs.
