Tel: 781.329.4700 Fax: 781.461.3113 www.analog.com Evaluation Board for Dual, High Speed Op Amps Offered in 8-Lead SOIC Packages external capacitors. The close spacing between the VCC supply FEATURES plane (Layer 3) and the inner ground plane (Layer 4) provides Enables quick breadboarding/prototyping the necessary capacitance to bypass the VCC supply. Similarly, User-defined circuit configuration the close spacing between the inner ground layer (Layer 4) and Edge-mounted SMA connector provisions the VEE supply plane (Layer 5) provides the necessary Easy connection to test equipment and other circuits capacitance to bypass the VEE supply. RoHS compliant The evaluation board components are primarily SMT 0603 case GENERAL DESCRIPTION size, with the exception of the electrolytic bypass capacitors (C1, The Analog Devices, Inc., 8-lead SOIC package, dual, high C2), which are 1206 case size. speed evaluation board is designed to help customers quickly Two options are available for supply bypassing. The first option prototype new dual op amp circuits and reduce design time. The is to use the internal interplanar capacitance. No external bypass evaluation board can be used with almost any Analog Devices capacitors are required. Capacitors C1 to C5 can be left off the dual op amp in various configurations and applications. The board. If additional supply bypassing is required, C1 and C2 can evaluation board is a bare board (that is, there are no components accommodate 1206 tantalum or nonpolarized capacitors. C3, or amplifier soldered to the board these must be ordered C4, and C5 accommodate 0603 capacitors. separately). Figure 1 shows the component side of the evaluation Figure 3 shows the evaluation board schematic. Figure 4 and board, and Figure 2 shows the circuit side of the evaluation board. Figure 5 show the evaluation board assembly drawings. This evaluation board is a 6-layer PCB, designed to provide internal, wideband, power supply bypassing without the use of EVALUATION BOARD COMPONENT AND CIRCUIT SIDES NOTES NOTES 1.
