The DEM-OPA68xU demonstration board is an unpopulated printed circuit board (PCB) for BurrBrown's high speed single op amps available in SO-8 packages. Figure 1 shows the pin out used for most of these op amps. Table I lists the exceptions to this pin-out that are also supported by this board. For more information on these op amps, and good PCB layout techniques, see the individual data sheets.
