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
R_F-amplifier circuits where parasitic capacitance and
inductance can have a major effect on circuit performance.
A SPICE model for the THS3201 is available through
either the Texas Instruments web site (www.ti.com) 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.
