2.2 FEATURES
The MCP43XXEV Evaluation Board has the following features:
• MCP4361-103E/ST is installed
• 0
Ω
resistors connect MCP4361 V
DD
and V
SS
signals to the appropriate Power or
Ground plane (see Figure 2-2)
• 0
Ω
resistors connect MCP4361’s Resistor Network 0 and 2 A terminal signal to
Power plane, Resistor Network is in a voltage divider configuration
(see Figure 2-2)
• 0
Ω
resistors connect MCP4361’s Resistor Network 0 and 2 B terminal signal to
Ground plane, Resistor Network is in a voltage divider configuration
(see Figure 2-2)
• Through-hole connection terminal (Orange) for all Wiper pins
