DESIGN-IN TOOLS

Macromodels and Applications Support

Computer simulation of circuit performance using SPICE is often a quick way to analyze the performance of the

capacitance and inductance can play a major role on circuit performance. A SPICE model for the OPA820 is

available through the TI web page (www.ti.com). The applications department is also available for design

assistance. These models predict typical small-signal AC, transient steps, DC performance, and noise under a

wide variety of operating conditions. The models include the noise terms found in the electrical specifications of

the data sheet. These models do not attempt to distinguish between the package types in their small-signal AC

performance.
