3.3.3
Solder onto the SOIC-8 pad shown in Figure 3-2. Pin 1 is on the top left (next to the U1
label). To avoid soldering and de-soldering many times, for slower parts, it may be
better to use the option discussed in Section 3.3.5 “Other Single Op Amps”.
3.3.4
Remove the original SOIC-8 packaged part. Solder a DIP-8 IC Socket in the PDIP-8
location shown on Figure 3-2; this makes it easy to change PDIP-8 parts. It also is
helpful for parts for other package and pinout options; see Section 3.3.5 “Other
Single Op Amps”. Figure 3-3 shows this board after the DIP-8 IC socket has been
installed.
FIGURE 3-3:
The socket may not work well in two cases (solder directly to the PCB instead):
• Very fast op amps (i.e., GBWP > 100 MHz)
• Very accurate op amps (i.e., V
3.3.5
With a DIP-8 IC Socket on the evaluation board (see Section 3.3.4 “Single Op Amps
in PDIP-8 Package”), it is relatively easy to adapt the MCP651 Input Offset Evaluation
Board to many other op amps. An adaptor board is stacked on top using headers that
solder to the adaptor board, using PDIP-8 through holes, and are inserted into the
DIP-8 socket on the evaluation board. The adaptor board can accommodate:
• Different packages
• Different pinout options (can be dealt with on the adaptor board)
• Parts with multiple op amps
The adaptor boards approach may not work well in two cases:
• Fast op amps (i.e., GBWP > 10 MHz); adding bypass capacitors to the adaptor
• Accurate op amps (i.e., V
