EVALUATION FIXTURES, SPICE MODELS,

AND APPLICATIONS SUPPORT

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

THS4500 family of fully differential amplifiers. The

evaluation board can be obtained by ordering through the

Texas Instruments web site, www.ti.com, or through your

local Texas Instruments sales representative. Schematic

for the evaluation board is shown below with their default

component values. Unpopulated footprints are shown to

provide insight into design flexibility.

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 THS4500 family of devices is

available through the Texas Instruments web site

(www.ti.com). The 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.
