Distortion is a key specification in communications applications.
Intermodulation distortion (IMD) is a measure of the ability of
an amplifier to pass complex signals without the generation of
spurious harmonics. T he third order products are usually the
most problematic since several of them fall near the fundamen-
tals and do not lend themselves to filtering. T heory predicts that
the third order harmonic distortion components increase in
power at three times the rate of the fundamental tones. T he
specification of third order intercept as the virtual point where
fundamental and harmonic power are equal is one standard
measure of distortion performance. Op amps used in closed-
loop applications do not always obey this simple theory. At a
gain of two the AD8001 has performance summarized in Figure
46. Here the worst third order products are plotted vs. input
power. T he third order intercept of the AD8001 is +33 dBm at
10 MHz

Operation as a Video Line Driver
T he AD8001 has been designed to offer outstanding perfor-
mance as a video line driver. T he important specifications of dif-
ferential gain (0.01%) and differential phase (0.025
°
) meet the
most exacting HDT V demands for driving one video load. T he
AD8001 also drives up to two back terminated loads, as shown
in Figure 47, with equally impressive performance (0.01%,
0.07
°
). Another important consideration is isolation between
loads in a multiple load application. T he AD8001 has more
than 40 dB of isolation at 5 MHz when driving two 75
back
terminated loads.
