The components of the evaluation board are primarily SMT 1206 case size, with the exception of the electrolytic bypass capacitors (C1, C4), which are 3528 case size. 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 evaluation board is designed to help users evaluate single, high speed op amps offered in 8-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 single op amp circuits, which minimizes risk and reduces time to market. The evaluation board is a 2-layer printed circuit board (PCB) that accepts SMA edge-mounted connectors on the inputs and outputs for efficient connection to test equipment or other circuitry. The evaluation board is designed to work with almost any of the Analog Devices op amps offered in an 8-lead SOIC package. The evaluation board can accommodate amplifiers that feature a power-down or disable pin. The board can also be used with op amps that feature external frequency compensation capacitors, such as the AD8021AR. Figure 1 shows the component side of the bare evaluation board, and Figure 2 shows the circuit side of the bare evaluation board. Figure 3 shows the evaluation board schematic. The assembly drawings are shown in Figure 4 and Figure 6. The recommended layout patterns for making connections to the op amp and supporting circuitry are shown in Figure 5 and Figure 7. Two options for supply bypassing include the following: 1. Connect additional shunt capacitors (C2, C5) in parallel with the electrolytic capacitors (C1, C4) from each supply to ground. This technique of power supply bypassing provides wideband rejection of unwanted noise on the supply lines. It is implemented by placing a 0 Ω resistor in the C6 position and shunt capacitors in the C1, C2, C4, and C5 positions. 2. Connect a capacitor between the supply rails. This method uses fewer components and can improve the PSRR at higher frequencies but does not provide shunt bypassing to the negative supply rail. It is implemented by inserting a 0 Ω resistor in the C2 position, then inserting the bypass capacitor in the C5 position, and omitting C6. Optimal bypassing is circuit dependent and, therefore, must be evaluated by the designer for each application. NOTES 1.
