Evaluation Fixtures and Application Support
Information
Texas Instruments is committed to providing its
customers with the highest quality of applications
support. To support this goal, an evaluation board
has been developed for the THS4281 operational
amplifier. The evaluation board is available and easy
to use allowing for straight-forward evaluation of the
device. These evaluation board can be obtained by
ordering through the Texas Instruments web site, or
through your local Texas Instruments Sales
Representative. A schematic for the evaluation board
is shown in Figure 77 with their default component
values. Unpopulated footprints are shown to provide
insight into design flexibility.

SLOS432A – APRIL 2004 – REVISED NOVEMBER 2009
Computer simulation of circuit performance using
SPICE is often useful when analyzing the
performance of analog circuits and systems. This is
particularly true for video and RF amplifier circuits
where parasitic capacitance and inductance can have
a major effect on circuit performance. A SPICE model
for the THS4281 device is available through either
the Texas Instruments web site or as one model on a
disk from the Texas Instruments Product Information
Center (1-800-548-6132). The PIC is also available
for design assistance and detailed product
information at this number. These models do a good
job of predicting small-signal ac and transient
performance under a wide variety of operating
conditions. They are not intended to model the
distortion characteristics of the amplifier, nor do they
attempt to distinguish between the package types in
their small-signal ac performance. Detailed
information about what is and is not modeled is
contained in the model file itself.
