The close spacing between the VCC supply plane (Layer 3) and the inner ground plane (Layer 4) provides the necessary capacitance to bypass the VCC supply. Similarly, the close spacing between the inner ground layer (Layer 4) and the VEE supply plane (Layer 5) provides the necessary capacitance to bypass the VEE supply. FEATURES Enables quick breadboarding/prototyping User-defined circuit configuration Edge-mounted SMA connector provisions Easy connection to test equipment and other circuits RoHS compliant GENERAL DESCRIPTION The Analog Devices, Inc., 8-lead SOIC package, dual, high speed evaluation board is designed to help customers quickly prototype new dual op amp circuits and reduce design time. The evaluation board can be used with almost any Analog Devices dual op amp in various configurations and applications. The evaluation board is a bare board (that is, there are no components or amplifier soldered to the board; these must be ordered separately). Figure 1 shows the component side of the evaluation board, and Figure 2 shows the circuit side of the evaluation board. This evaluation board is a 6-layer PCB, designed to provide internal, wideband, power supply bypassing without the use of The evaluation board components are primarily SMT 0603 case size, with the exception of the electrolytic bypass capacitors (C1, C2), which are 1206 case size. Two options are available for supply bypassing. The first option is to use the internal interplanar capacitance. No external bypass capacitors are required. Capacitors C1 to C5 can be left off the board. If additional supply bypassing is required, C1 and C2 can accommodate 1206 tantalum or nonpolarized capacitors. C3, C4, and C5 accommodate 0603 capacitors. Figure 3 shows the evaluation board schematic. Figure 4 and Figure 5 show the evaluation board assembly drawings. NOTES 1.
