APPLICATION INFORMATION
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 THS408x 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 41. A minimum value of 20
should work well for most applications. For
example, in 75-
transmission systems, setting the series resistor value to 75
both isolates any capacitance
loading and provides the proper line impedance matching at the source end.

offset voltage
The output offset voltage, (V

) times
the corresponding gains. The following schematic and formula can be used to calculate the output offset
