APPLICATION INFORMATION
data converters (continued)
Some single supply applications may require the input voltage to exceed the common-mode input voltage
range. In such cases, the following circuit configuration is suggested to bring the common-mode input voltage
within the specifications of the amplifier.

driving a capacitive load
Driving capacitive loads with high-performance amplifiers is not a problem as long as certain precautions are
taken. The first is to realize that the THS414x has been internally compensated to maximize its bandwidth and
slew rate performance. When the amplifier is compensated in this manner, capacitive loading directly on the
output will decrease the device’s phase margin leading to high-frequency ringing or oscillations. Therefore, for
capacitive loads of greater than 10 pF, it is recommended that a resistor be placed in series with the output of
the amplifier, as shown in Figure 25. A minimum value of 20
should work well for most applications. For
example, in 50-
transmission systems, setting the series resistor value to 50
both isolates any capacitance
loading and provides the proper line impedance matching at the source end.
