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
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
are located below device U2. The layout allows through-hole connection posts.
2.4.2
The MCP4XXX Digital Potentiometer Daughter Board has pads for all the resistor net-
work signal. These are:
There are three pads for control signals that are also available:
• U1-CS0/U3-CS
• U2-CS1
• U3-UD
2.4.3
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.
