INTRODUCTION
Chapter 2. Installation and Operation
The MCP46XXEV Evaluation Board allows the system designer to quickly evaluate the
operation of the MCP4661 10 kΩ (-103) digital potentiometer device using the PICkit
Serial Analyzer. The PICkit Serial Analyzer is available separately (order number:
DV164122).
This 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 board can also be very easily jumpered into a customer’s existing circuit. This
gives an indication of the MCP4661 device performance, but is affected by the jumper
lead length and the EM noise that the jumpers pick up.
The MCP4661 has two resistor networks. The device’s Resistor Network 0 has been
configured in a Potentiometer mode with the A terminal connected to V
resistor and the B terminal connected to V
be evaluated for rheostat operation.
The MCP46XXEV Evaluation Board uses the generic TSSOP20EV Evaluation Board
PCB. The kit includes a second PCB which is blank for the user to populate as desired.
Additional PCBs may be ordered (order number: TSSOP20EV). The TSSOP20EV kit
includes 5 blank PCBs.
Other boards can easily be built up using the TSSOP20EV PCB to allow evaluation of
other resistance options (5 kΩ, 50 kΩ, or 100 kΩ) or any of the other digital
potentiometer devices in the following packages:
• TSSOP-20 package
• TSSOP-14 package
The 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 TSSOP20EV Evaluation Board PCB or for
modifying the MCP46XXEV Evaluation Board is available in the TSSOP20EV User’s
Guide (DS51875). Appendix A. “Schematic and Layouts” has information on the
PCB schematic and layout while Figure 2-2 shows components that are installed on the
PCB.
