JUMPER
STATE
FUNCTION
JU1
Closed*
Use CalGain inputs for gain calibration (CALGAIN+ = REFIN+)
JU2
Closed*
Use CalGain inputs for gain calibration (CALGAIN- = REFIN-)
JU3
Closed*
Use CalOff inputs for offset calibration (CALOFF+ = GND)
JU4
Closed*
Use CalOff inputs for offset calibration (CALOFF- = GND)
JU5
Closed*
Use on-board reference U2 (REFIN- = GND)
JU6
Open
Disconnects pin 5 from pin 7
MAX1402: pin 5 = digital input DS1, pin 7 = current source
MAX1400: insert filter between mux and A/D
JU7
Open
Disconnects pin 6 from pin 8
MAX1402: pin 6 = digital input DS0, pin 8 = current source
MAX1400: insert filter between mux and A/D
JU8
Closed*
Use on-board reference U2 (REFIN+ = 2.5V)
*Default trace on top layer of PCB.
