Input / Output Isolation vs. Frequency..
Choice of the Feedback Circuit
The TSH11x is a serie of current feedback
amplifiers. For a current feedback structure the
bandwidth depends on the value of the feedback
components and the value of supply voltage.
A good choice of these components is necessary
to achieve the gain flatness and the stability.
The following table shows the typical -3dB
bandwidth and 0.1dB bandwidth assuming
different gains and power supply on 100
load.
Please see also the Closed Loop Gain vs.
Frequency curves on page 8 of the datasheet.

Non-inverting and Inverting Implementation.
.
(tab.1):
Closed-loop Gain and Feedback Components.
Inverting Amplifier Biasing
In this case a resistance (R on fig.40) is necessary
to achieve a good input biasing.
This resistance is calculated by assuming the
negative and positive input bias current. The aim
is to make the compensation of the offset bias
current which could affect the input offset voltage
and the output DC component.
Assuming Ib-, Ib+, R

and a zero volt output,
the resistance R comes : R = R
