12.1 Device Support

12.1.1 Development Support

12.1.1.1 Demonstration Boards

A printed circuit board (PCB) is available to assist in the initial evaluation of circuit performance using the VCA810. This evaluation board (EVM) is available free, as an unpopulated PCB delivered with descriptive documentation. The summary information for this board is shown in the DEM-VCA-SO-1A user's guide.

12.1.1.2 Macromodels and Applications Support

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 play a major role in circuit performance. A SPICE model for the VCA810 is available through the TI web page. The applications group is also available for design assistance. The models available from TI predict typical small-signal AC performance, 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 relevant product data sheet.
