APPLICATION INFORMATION
offset voltage
The output offset voltage, (V
OO
) is the sum of the input offset voltage (V
IO
) and both input bias currents (I
IB
) times
the corresponding gains. The following schematic and formula can be used to calculate the output offset
voltage:

optimizing unity gain response
Internal frequency compensation of the THS404x was selected to provide very wideband performance yet still
maintain stability when operated in a noninverting unity gain configuration. When amplifiers are compensated
in this manner there is usually peaking in the closed loop response and some ringing in the step response for
very fast input edges, depending upon the application. This is because a minimum phase margin is maintained
for the G=+1 configuration. For optimum settling time and minimum ringing, a feedback resistor of 200
should
be used as shown in Figure 68. Additional capacitance can also be used in parallel with the feedback resistance
if even finer optimization is required.
