NOTES:
1.
All resistors 1% low noise unless noted.
2.
Middle button switch is optional.
3.
Jumper JMP1 is only installed when middle button is not present, otherwise it is not populated.
4.
Connectors are shown for reference only.
5.
Connection between analog and digital ground must be a single point connection close to the TPM754.
6.
Component values that are not specified depend upon stick sensitivity, geometry, impedance, and tolerance.
7.
TPM754 Reset pin (Pin 5) can be driven by system power on reset signal (active High). Omit C4, R 8 in this case.
8.
If Pin 3 is grounded, positive voltage swing on the stick’s Y terminal will move the cursor downward (–Y), otherwise upward.
9.
If Pin 28 is grounded, positive voltage swing on the stick’s terminal will be interpreted as downward (–Z) force, otherwise upward.
10.
A Z axis series resistor and a fifth stick terminal may be present.
