EVM

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 THS4631 is

available through either the Texas Instruments web site (www.ti.com). These models help in 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.
