Table 5-1 lists the functionality and default configuration of each jumper.

Table 5-1 Default Jumper Configurations
Reference Designator Default Configuration Description
JP1, JP2, JP3, JP4 Open Use pin 1 of these jumpers as an alternate location to provide the analog input to ADC A and ADC B of the ADS8354.
JP5, JP6 Closed Jumpers to feed either VREF or VREF / 2 to the OPA320 input driving the THS4561 common-mode voltage (VOCM) pin. See Section 7.3 for more details.
JP7, JP8 Open Short these pins to use the REF6025 external reference voltage. See Section 4.2 for more details.
JP9 Closed [1-2] By default, AVSS (negative supply rail of the THS4561) is set to a –232-mV supply generated by the LM7705. Shorting JP9[2-3] sets AVSS to GND.
JP10 Closed Jumpers to feed either GND or 5.5 V to the shutdown (SD) pin of the LM7705. By default, GND is used to keep the SD pin low, so the LM7705 device is on. See the LM7705 data sheet for more details.
