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 
external capacitors. 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. 
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.
