11.1 Layout Guidelines

Make all power connections with short, low impedance connections.

Depending on the application, the design might benefit from having the OPT101 mounted to the opposite side of the board as the other electrical components. Keeping the optical sensor side free from extra components allows for easier mounting of any required optical-mechanical structures around the OPT101.

11.2 Layout Example

The following example shows an external feedback network (R2 and C2) that bypasses the internal feedback network, similar to Figure 19. This example also shows an external feedback network (R1, C1) in series with the internal feedback network, similar to Figure 18. To use only the internal feedback network, load R1 or C1 with a short circuit. This example allows for three different configurations with the same layout. Do not load R1, C1, R2, and C2 simultaneously.
