DESCRIPTION
JU10
1-2* Connects the OVDD input of the ADC (U1) to the output of the on-board 3.3V LDO.
2-3 Connects the OVDD input of the ADC (U1) to the OVDD connector.
JU11
1-2* Connects the output of U17 (3.0V) to the REF input of the device.
2-3 Connects the REF pin of the ADC (U1) to the REF connector.
JU12
1-2* Connects the SCLK signal of the ADC (U1) to the FPGA.
2-3 Connects the SCLK signal of the ADC (U1) to the SCLK connector.
JU13
1-2* Connects the DOUT signal of the ADC (U1) to the FPGA.
2-3 Connects the DOUT signal of the ADC (U1) to the DOUT connector.
JU14
1-2*
Connects the CS signal of the ADC (U1) to the FPGA.
2-3
Connects the CS signal of the ADC (U1) to the CS connector.
JU15
1-2* Connects the CHSEL signal of the ADC (U1) to the FPGA.
2-3 Connects the CHSEL signal of the ADC (U1) to the CHSEL connector.
JU16
1-2* Connects the AVDD input of the ADC (U1) to the output of the on-board 3.3V LDO.
2-3 Connects the AVDD input of the ADC (U1) to the AVDD connector.
JU17
1-2 Connects OP- to GND. Use this jumper if the negative supply is not available.
Open* Disconnects OP- from GND.
JU18
1-2*
Bypasses the on-board input buffer. Connects the AIN1_DC_SMA or the AIN1_DC connector to the
AIN1 input of the ADC (U1).
2-3 Connects the AIN1 input of the ADC (U1) to the output of the on-board buffer (U9).
JU19
1-2 Shorts the AC signal input to GND.
Open*
Connects the signal from the AIN1_AC_SMA connector to the inverting input of the on-board buffer
(U9) through a 1kI resistor.
JU20
1-2 Shorts the DC signal input to GND.
Open*
Connects the signal from the AIN1_DC_SMA connector to the noninverting input of the on-board
buffer (U9) through a 1kI resistor.
JU21
1-2*
Bypassing the on-board input buffer. Connects the AIN2_DC_SMA or the AIN2_DC connector to the
AIN2 input of the ADC (U1).
2-3 Connects the AIN2 input of the ADC (U1) to the output of the on-board buffer (U16).
JU22
1-2 Shorts the DC signal input to GND.
Open*
Connects the signal from the AIN2_DC_SMA connector to the noninverting input of the on-board
buffer (U16) through a 1kI resistor.
JU23
1-2 Shorts the AC signal input to GND.
Open*
