INTRODUCTION
The MCP401XEV Evaluation Board allows the system designer to quickly evaluate the
operation of the MCP40D18 10 k
Ω
(-103) Digital Potentiometer device using the PICkit
Serial Analyzer. The PICkit Serial Analyzer is available separately (order number:
DV164122).
The MCP401XEV Evaluation Board is a minimum configuration for the device. As well
as the device, other desired passive components (resistors and capacitors) and
connection posts may be installed.
The MCP401XEV Evaluation Board can also be very easily jumpered into a customers
existing circuit. This gives an indication of the MCP40D18 device performance, but is
affected by the jumper lead length and the EM noise that the jumpers pick up.
The MCP401XEV Evaluation board uses the generic SC70EV Evaluation Board PCB,
and includes a second blank PCB. Additional PCB may be ordered (order number:
SC70EV). The SC70EV kit includes 5 blank PCBs.
Other boards can be easily built up using the SC70EV PCB to allow evaluation of other
resistance options (5 k
Ω
, 50 k
Ω
, or 100 k
Ω
) or any of the other devices in the following
packages:
• SC70 package (uses I
2
C interface)
- MCP4017, MCP4018, MCP4019, MCP40D17, or MCP40D19
• SOT-23 package (uses Up/Down interface)
- MCP4012, MCP4013, MCP4014, MCP4022, MCP4023, or MCP4024
• DIP-8 Package (uses SPI interface)
- MCP4131, MCP4141, MCP4151, or MCP4161
The MCP401XEV Evaluation Board also has a 6-pin interface (PICkit Serial, ICSP, etc.)
whose signals can easily be jumpered to any of the device’s pins.
Additional information on using the SC70EV Evaluation Board PCB or for modifying the
MCP401XEV board is available in the SC70EV User’s Guide (DS51874).
has information on the PCB schematic and layout while
Figure 2-2 shows components that are installed on the PCB.
