LINE DRIVER MODE
iC-MZ’s line driver mode is activated by TEST = high,
i.e. by a supply of VPA = 5 V. Pins A and NA then func-
tion as independent inputs for line driver outputs D and
4.5 ... 36 V
ND. When pins A and NA are connected together and
used as common input, D and ND acts as buffered and
inverted outputs.
