GENERAL DESCRIPTION 
The Analog Devices, Inc., 14-lead SOIC evaluation board is 
designed to help users evaluate quad, high speed op amps 
offered in 14-lead SOIC packages. The evaluation board is a 
bare board (that is, there are no components or amplifier soldered 
to the board; these must be ordered separately) that enables users 
to quickly prototype a variety of quad op amp circuits. The 
evaluation board minimizes risk and reduces time to market. 
Figure 1 shows the component side of the bare evaluation  
board, and Figure 2 shows the circuit side. 
The 2-layer evaluation board accepts SMA edge-mounted 
connectors on the inputs and outputs for efficient connection  
to test equipment or other circuitry. The ground plane, component 
placement, and supply bypassing are designed to minimize parasitic 
inductance and capacitance. The evaluation board components 
are primarily SMT 0805 case size, with the exception of the 
electrolytic bypass capacitors (C1 and C2), which are 3528 case size. 
Figure 3 shows the evaluation board schematic. The PCB 
assembly drawings are shown in Figure 4 and Figure 5. The 
layout patterns for the PCB are shown in Figure 6 and Figure 7.
