ANALOG INPUT STRUCTURE
UNIVERSAL SERIAL BUS (USB)
Two differential input paths allow external signal sources to be easily connected to the
MCP3901 input. Edge connectors JP1 and JP2 are 3-pin connectors that act both as
crew type and clip on post connectors.
JP1 and JP2 can be used to force either channel from a differential to single-ended
configuration. R3 and R4 (on CH0), and R1 and R2 (on CH2) act as locations for
burden resistor connectors for any current transformer inputs.
The MCP3901 ADC Evaluation Board for 16-Bit MCUs also contains a USB connection
for higher speed sampling and data collection. The circuit includes a 512x8 SRAM for
data collection. Figure 1-5 summarizes the connections between the ADC, the two
microcontrollers and memory.

To use an edge connector as a post connector, pull up the blue plastic top
to access posts.
For the MCP3901 ADC Evaluation Board for 16-Bit MCUs release, no USB
firmware is supplied. The PIC18F86J55 is blank and only included for
development purposes.
