2.4.4
Jumper JP2 is located in the center of the board above JP1. JP2 consists of three pairs
of jumper pins. The lower two pins are connected to A
connected to V
Appendix A. “Schematics and Layouts”.
If the user would like to read Microchip’s MCP492X or MCP482X DAC A output with
either the MCP3302 or MCP3204, place a jumper from one of the middle two pins to
either of the outer pins, depending on which ADC input channel you are using.
2.4.5
Jumper JP3 is located in the center of the board just above the 8-pin, dual op amp
MCP617 and to the right of the SMA connector’s footprint. JP3 consists of three pairs
of jumper pins. The lower two pins are connected to A
connected to V
Appendix A. “Schematics and Layouts” to view the schematic.
If the user would like to read Microchip’s MCP492X or MCP482X DAC B output with
either the MCP3302 or MCP3204, place a jumper from one of the middle two pins to
either of the outer pins, depending on which ADC input channel you are using.
2.4.6
Jumper JP4 is located in the center of the board, farthest away from the PICmicro
microcontroller and its MPLAB ICD 2 connector. JP4 consists of three pairs of jumper
pins. The lower two pins are connected to the MCP1541’s 4.1V V
two pins are connected to the REF198G’s 4.1V V
NOT connected, similar to J1, J2 or J3. The middle left pin selects the V
source while the middle right pin selects the V
Appendix A. “Schematics and Layouts”.
If the user employs the REF19G as the V
TC132X DACs, a jumper connecting the top right pin with the middle right pin is
required. If the user would like to use the MCP1541 as the V
MCP492X, MCP482X or TC132X DACs, a jumper connecting the bottom right pin with
the middle right pin is required.
If the user employs the REF19G as the V
MCP3204 or PIC16F767 ADCs, a jumper connecting the top right pin with the middle
right pin is required. If the user employs the MCP1541 as the V
Microchip’s MCP492X, MCP482X or TC132X DACs, a jumper connecting the bottom
right pin with the middle right pin is required.
