MCP4XXX DIGITAL POTENTIOMETER DAUGHTER BOARD DESCRIPTION
The MCP4XXX Digital Potentiometer Daughter Board PCB is designed to be flexible in
the type of device evaluation that can be implemented.
The following sections describe each element of this evaluation board in further detail.
2.4.1
Power and Ground
The MCP4XXX Digital Potentiometer Daughter Board receives its power over the J3
header connector. If the board is to be jumpered into an existing application, then the
board can have connection posts installed for the power (V DD ) and ground (V SS ), which
are located below device U2. The layout allows through-hole connection posts.
2.4.2
Connection Pads
The MCP4XXX Digital Potentiometer Daughter Board has pads for all the resistor net-
work signal. These are:
U1-P0A
U1-P0W
U1-P0B
U1-P01A
U1-P1W
U1-P1B
U2-P0A
U2-P0W
U2-P0B
U2-P01A
U2-P1W
U2-P1B
U3-1A
U3-W
Socket U1

There are three pads for control signals that are also available:
? U1-CS0/U3-CS
? U2-CS1
? U3-UD

Passive Components (R1, R2, R3, R4, R5, R6, R7, R8, R9, R10,
R11, R12, R13, R14, R15 and R16)
The footprints for these components are present to allow flexibility in the use of fixed
resistors for the windowing of the U1-Pot0 (or U3-Pot) to better match your system
requirements.
