For flexibility, the EVM provides optional capacitors C4 and C18. These capacitors are in parallel with the PGA855 output-stage internal-feedback resistors to implement noise filtering. In addition, the evaluation board provides footprints R6, R10, C9, C5, and C12 for optional input low-pass filters, and footprints for load resistors R7 and R11. These additional component footprints in the layout allow the user to customize the evaluation circuit. For a full schematic of the PGA855EVM, see Figure 8-1.
