APPLICATIONS
High output current drive capability (6Vp-p into 75
)
allows two back-terminated 75
transmission lines
to be simultaneously driven.

NOTE: The value of R
S
varies with the value of the input capacitance of
the A/D converter. R
S
is 0
for the ADC614 since the input capacitance
in only 5pF.
