13 Device and Documentation Support

13.1 Device Support

13.1.1 Design-In Tools

13.1.1.1 Demonstration Fixtures

Two printed-circuit boards (PCBs) are available to assist in the initial evaluation of circuit performance using the OPA820 device in the two package options. Both of these boards are offered free of charge as unpopulated PCBs, delivered with a user’s guide. Table 3 lists a summary information for these fixtures.

Table 3. Demonstration Fixtures

DEVICE NUMBER PACKAGE ORDERING NUMBER USER'S GUIDE
OPA820 SOIC (8) DEM-OPA-SO-1A DEM-OPA-SO-1A Demonstration Fixture
OPA820 SOT-23 (5) DEM-OPA-SOT-1A DEM-OPA-SOT-1A Demonstration Fixture

The demonstration fixtures can be requested through the OPA820 product folder.

13.1.1.2 Macromodels and Applications Support

Computer simulation of circuit performance using SPICE is often a quick way to analyze the performance of the OPA820 device and the device circuit designs. This is particularly true for video and RF amplifier circuits where parasitic capacitance and inductance can play a major role on circuit performance. A SPICE model for the OPA820 device is available through 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.
