The boards are designed with good layout, grounding, and decoupling techniques. They are completely tested, and artwork (including Pg tape is available to customers Because of the popularity of dual precision op amps in 8-pin DIPs, a universal evaluation board has been developed(see Figure 9.9). This board makes extensive use of pin sockets to allow resistors or jumpers to configure the two op amps in just about any conceivable feedback, input/output, and load condition. The inputs and outputs are convenient right-angle bnc connectors. Because of the use of sockets and the less-than- compact layout, this board is not useful for op amps having gain bandwidth products much greater than 10MHz.1 0 SUCCESSFUL PROTOTYPING Always use a ground plane for precision or high frequency circuits Minimize parasitic resistance, capacitance, and inductance If sockets are required, use “pin sockets” (“cage jacks”) Pay equal attention to signal routing, component placement, grounding, and decoupling in both the prototype and the final design Popular prototyping techiniques: Freehand “deadbug” using point-to-point wiring “Solder-Mount” Milled PC board from CAD layout Multilayer boards: Double-sided with additional point-to￾point wiring Figure 9.8 EVALUATION BOARDS Manufacturer's evaluation boards provide a convenient way of evaluating high￾performance ICs without the need for constructing labor-intensive prototype boards.
