Evaluation Board for Dual, High Speed Op Amps
Offered in 8-Lead SOIC Packages
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.
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.
