Figure 2-18. Ground Reference Jumper Position for Use with the PC-LPM-16
The application information given for MIO-16 in the RSE input mode also applies to the
PC-LPM-16.
MIO-16 Analog Output
Analog output BNC connectors each have two open component positions for optional signal
conditioning components. One of these is designated as a resistor and the other as a capacitor.
The equivalent circuit for DAC0 OUT is shown in Figure 2-19. DAC1 OUT circuitry is identical
to that of DAC0 OUT.
When the board is shipped, 0-
1
jumpers are inserted into the
R9
position. These can be easily
removed to build passive analog output signal conditioning circuits such as voltage dividers and
lowpass filters.
