The evaluation board is a bare board (that is, there are no components soldered to the board; these must be ordered separately). Figure 1 and Figure 2 show component side and circuit side of the bare evaluation board. Figure 3 shows the evaluation board schematic. The evaluation board is fabricated in a 4-layer printed circuit board (PCB). It accepts edge-mounted Subminiature A (SMA) connectors on the inputs and outputs, which allows efficient connection to test equipment and other circuits. The evaluation board components are primarily SMT 1206 case size, with the exception of the tantalum bypass capacitors (C3, C4), which are D (C7343) size. Figure 4 and Figure 5 show the component side and circuit side of the evaluation board assembly drawing. Figure 6 and Figure 7 show the metal layout pattern for connecting the board to the current sense amplifier and to the supporting circuitry. Rev 14 May 2014 17:30 | Page 1 Figure 1.
