Coax cables with a typical impedance of 50W or 75W are
used in many applications to ensure signal fidelity, and highspeed
line drivers have the often difficult job of transmitting
signals over these cables or over twisted pair lines. The most
common way to drive coax cables is to use driver amplifiers
with low-impedance voltage output, which operate with
either voltage or current feedback. Now, however, the
wideband OTAs, OPA660 and OPA2662, offer a highimpedance
current output, giving engineers more flexibility
and more options. Since both voltage and current outputs
have their advantages and disadvantages, engineers can
choose the method that provides the best compromise for
their applications.
