DEM-OPA-SO-1A Demonstration Fixture
1 Description
The DEM-OPA-SO-1A demonstration fixture is a generic, unpopulated printed circuit board (PCB) for
single operational amplifiers in SO-8 packages. Figure 1 shows the package pinouts supported by this
PCB. For more information on any individual op amps, as well as good PCB layout techniques, see the
individual amplifier data sheets.
Figure 1. SO Package Pinout, Top View
As seen in Figure 1, this generic board supports these major variations: (a) standard SO-8 pinout; (b)
standard SO-8 pinout with disable/shutdown; and (c) standard SO-8 pinout with limiters.
2 Circuit
The circuit schematic in Figure 2 shows the connections for all possible components. Each configuration
uses only some of the components.
