where parasitic capacitance and inductance can have
a major effect on circuit performance. A SPICE model
for the THS3091/5 is available through the Texas
Instruments Web site (www.ti.com). The Product
Information Center (PIC) is also available for design
assistance and detailed product information. 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.
