FEATURES
GETTING STARTED
The MCP3905/6 Evaluation Board has the following features:
• Large space for easy connection to AC line and loads provide area for
• Easy connection to both PICDEM™ demonstration boards for a variety of
• Jumpers and shunts for simple device configuration
• On-board, low-cost AC-to-DC power supply circuitry to demonstrate the low-cost
• EMC immunity and Printed Circuit Board (PCB) design as used in the MCP3905/6
• Designed to fit inside recommended plastic enclosure for safe, high-voltage
The following example is given to describe how to use this evaluation board using a
current-sensing shunt, 220 VAC line voltage and a 10A load. All connections described
in this section are dependent on the choice of current-sensing element. A 250 µΩ shunt
is selected as the current-sensing element.
2.3.1
Use the input prototype area to connect the line/load and current-sensing elements to
the appropriate screw-type connector. An example of connecting the shunt is shown in
Figure 2-2. Please note that the phase-side of the line should be used as the GND
reference to the MCP3905/6 Evaluation Board when using the AC/DC power supply
circuit in shunt examples like the one in Figure 2-2.
