WHAT IS THE MCP46XX PICTAIL™ PLUS DAUGHTER BOARD?
The MCP46XX PICtail™ Plus Daughter Board is used to demonstrate the use of digital
potentiometers. This board is designed to be used in conjunction with either the
Explorer 16 Development Board or the PICkit™ Serial Analyzer. Figure 1-1 shows the
board’s components placement and the purpose of the jumpers.
The board has an MCP4261-103 (10 kΩ ) device for evaluation. This device is in the
TSSOP package (U2). This is a dual 8-bit Non-Volatile Potentiometer device. The
MCP4661 uses an I
interface (J1) or via the PICtail Plus interface (J3).
When using the PICtail Plus interface, the HVC voltages can be taken to a V
for high voltage commands. This is done by controlling the selection of the analog
switch device (U1).
Jumpers allow the Terminal A and Terminal B voltages to be tied to AVDD and VSS, or
come from an external source.
