OVERVIEW
The MCP3901 Low-Cost Power Monitor Reference Design is used to evaluate the per-
formance of the MCP3901 dual channel ADC, as well as a development platform for
PIC18F-based applications. A programmed PIC18F25K20 device in the power monitor
processes samples acquired by the MCP3901 to obtain Root Mean Square Voltage
(U
Factor values.
