Components that are shown in the partial schematic (see Figure 10-8) should be placed as close as possible to the respective device pins. Avoid long traces, because they add additional parasitic capacitance, inductance, and resistance on the signal. Avoid routing analog input signals close to a high-frequency pin (for example, a high-frequency PWM), because the high-frequency switching can be coupled into the analog signal. When possible, use internal connections to other modules to limit the potential of error introduction.
