Function
Selection of the IN+ analog signal of U1 and U8, ADC0 and ADC1.
Position AMP+ = the signal present on JP13, buffered through U6.
Position not in AMP+ = optional multiplexer output, DB, is used.
Selection of JP3 source.
Position AMP- = the signal present on JP25, buffered through U7.
Position not in AMP- = optional multiplexer output, DA, is used.
Selection of the IN? analog signal of U1.
Position Unip = single-ended ADC: AD7683, AD7685, AD7694, AD7942, AD7946, AD7980.
Position Diff = true differential ADC: AD7684, AD7687, AD7688, AD7690, AD7691, AD7693,
AD7982.
Selection of the reference voltage.
Position ADR43X = on board 5V reference voltage is used.
Position VDD = the ADC reference is coming from the VDD supply.
Selection of the reference voltage.
Positon NO BUF = refence present on JP4 (ADR43X or VDD) is selected
Position BUF = buffered reference present on JP4 (ADR43X or VDD) is selected. This buffer
( AD8032 ) can help to filter the VDD when used as the reference voltage.
Selection for negative supply, VDRV.
Selection for positive supply, VDRV+.
Selection for reference circuit supply, VREF.
Selection for digital output interface voltage, VIO.
Selection for ADC, U1 and U8 supply VDD.
Selection for FPGA output interface voltage VIO. Must be set at VIO or 3.3V which ever is the
lowest.
Selection of JP1 source
BUF+ = U6 amplifier output.
SMB+ = direct input from J1, AIN+ (SMB plug).
DIF+ = optional differential amplifer + output.
Selection of JP2 source
BUF- = U7 amplifier output.
SMB- = direct input from J2, AIN-(SMB plug).
DIF- = optional differential amplifer - output.
