setting
J1 1 - 2 Closed Connects V
DUT
and VS+ supply lines together
J3 Sensor
supply
1 - 2 Closed Use this setting to power the sensor with the V
DUT
supply.
2 - 3 Open Use this setting to supply sensor power from an
external source (e.g. DAC1).
J4 CS 1 - 2 Open Enable function (EN); use to place the MCP6N16 into
power-down by installing this jumper.
J6 1 - 2 Closed Connects the SENSE+ line to the VB+ line
5 - 6 Closed Connects the SENSE- line to the VB- line
3 - 4 Open Optional: when installed shortens the AIN+ and AIN-
inputs together.
May be used for diagnostic purposes.
J8 +3.3V
ext.
1 - 2 Open Use only when power will be supplied by the PIC
®
microcontroller attached through J12. Not needed for
stand-alone bench operation.
J9 Gain
Select
1 - 2 Closed Configures the MCP6N16 for a gain of +101V/V
2 - 3 Open Configures the MCP6N16 for a gain of +301V/V
J10 VCM 1 - 2 Closed Connects the external V
CM
(from J2) to the signal
inputs through R13 and R14
2 - 3 Open Use this to provide a DC-path for the INA inputs when
the signal is AC-coupled. (
Section 2.4.3.1 “Input
AC-Coupling”
)
J11 VREF 1 - 2 Open Use this to reference V
REF
pin of the MCP6N16 to
ground
2 - 3 Closed In this setting the output of the MCP6N16 will be level
shifted by the external V
REF
voltage.
J13 1 - 2 Open Use this setting in conjunction with the DigiPot
MCP4018. This function is only available when the
PIC
®
microcontroller is attached at J12.
2 - 3 Closed Connects the adjustable reference voltage to the buffer
amp U4
