Overload Recovery
The three important overload conditions are: input common-
mode voltage overdrive, output voltage overdrive, and input
current overdrive. When configured for a low closed-loop gain,
the amplifier will quickly recover from an input common-
mode voltage overdrive; typically in under 25 ns. When con-
figured for a higher gain, and overloaded at the output, the
recovery time will also be short. For example, in a gain of +10,
with 15% overdrive, the recovery time of the AD8013 is about
20 ns (see Figure 30). For higher overdrive, the response is
somewhat slower. For 6 dB overdrive, (in a gain of +10), the
recovery time is about 65 ns.

As noted in the warning under “Maximum Power Dissipation,”
a high level of input overdrive in a high noninverting gain circuit
can result in a large current flow in the input stage. Though this
current is internally limited to about 30 mA, its effect on the
total power dissipation may be significant.
High Performance Video Line Driver
At a gain of +2, the AD8013 makes an excellent driver for a
back terminated 75
differential gain and phase errors and wide 0.1 dB bandwidth
can be realized. The low gain and group delay matching errors
ensure excellent performance in RGB systems. Figures 34 and
35 show the worst case matching.
