Typical Performance Characteristics
OVERDRIVE RECOVERY
When the output or input voltage range of a high speed amplifier is exceeded, the amplifier must recover from an
overdrive condition. The typical recovery times for open-loop, closed-loop, and input common-mode voltage
range overdrive conditions are illustrated in Figure 90, Figure 92, and Figure 93, respectively.
The open-loop circuit of Figure 89 generates an overdrive response by allowing the ±0.5V input to exceed the
linear input range of the amplifier. Typical positive and negative overdrive recovery times shown in Figure 90 are
5 ns and 25 ns, respectively.

and 25 ns from Test Circuit in Figure 89
The large closed-loop gain configuration in Figure 91 forces the amplifier output into overdrive. Figure 92
displays the typical 30 ns recovery time to a linear output value.
