Evaluation Board for Dual High Speed Op Amps
Offered in 16-Lead 3 mm × 3 mm LFCSP
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., 16-lead LFCSP evaluation board
is designed to help users evaluate dual high speed op amps
offered in 16-lead, 3 mm × 3 mm LFCSP 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 dual op amp circuits, which minimizes risk and
reduces time to market. Figure 1 and Figure 2 show the bare
evaluation board component and circuit sides.
The evaluation board is a 2-layer PCB that 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 inductances and capacitances.
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 evaluation
board assembly drawings and layout patterns are shown in
Figure 4 through Figure 7.
