2.3.1.2 PASSIVE COMPONENTS

Table 2-1 shows the optional passive components (resistors) that are by default not

populated. Use the schematic to determine which resistors and values are required for

your custom configuration.

R2, R3, R5, R7, R9, R10,

R13, R15, R16

Pull-up resistor

R1, R4, R11, R12, R14 Pull-down resistor

R20, R21 In-line resistor. Connected between the U1 wiper outputs and

the PICDEM 28-pin header (H3) A/D pins. This is default open

due to the PICDEM Demo Boards may have circuitry on these

pins which would effect the wiper operation. If these are

installed (typically with a 0Ω resistor), ensure that the PICDEM

board has been appropriately modified so that the wiper signal

is not effected.
