LINK CONFIGURATION OPTIONS

Multiple link options must be set correctly to select the appropriate
operating setup before using the EVAL-AD7386FMCZ. The
functions of these options are detailed in Table 2.
Table 2. Link Options for EVAL-AD7386FMCZ
Link
Name Function
LK1 Internal or external selection for the negative
supply of the amplifier
LK2 Internal or external selection for the positive
supply of the amplifier
LK3 Internal or external selection for 12 V supply
LK4 Selection for external voltage reference (V
LK5 Selection for logic voltage (V
JP1, JP2 Amplifier selection for A
JP3, JP6 Amplifier selection for A
JP4 Internal or external selection for V
JP5 Internal or external selection for V
Position refers to the pin on the link. For example, Positon 3-4 means Pin 3 and Pin 4 of the link is shorted by a header stub, and the SMD resistor is the surface-mount
1
device resistor.

Setup Conditions
Ensure that all link positions are set as required by the selected
operating mode before applying power and signals to the
evaluation boards. Table 2 shows the default positions of the
links when the EVAL-AD7386FMCZ is packaged.
Position 1 Description
1 Use the internal −5 V from the
Change to Position 3 to use the external supply.
1 Use the internal 5 V from the
Change to Position 3 to use external supply.
1 Use the 12 V power supply from the EVAL-SDP-CH1Z.
Change to Position 3 to use the external supply.
3-4 Use the internal 3.3 V from the
Change to Position 1-2 (link shorted on Pin 1 and Pin 2)
to use the external reference.
Change to Position 5-6 (link shorted on Pin 5 and Pin 6)
to use the ADR4525.
3-4 Use internal 2.3 V from the
Change to Position 1-2 to use the external reference.
Change to Position 5-6 to use VLOGIC from the
EVAL-SDP-CH1Z.
1 (SMD resistor) Use on-board amplifier for signal conditioning.
Change to Position 3 to use an amplifier mezzanine card
(AMC).
1 (SMD resistor) Use on-board amplifier for signal conditioning.
Change to Position 3 to use an AMC.
3 (SMD resistor) Use the internal voltage reference of the AD7386. Change
to Position 2 to use an external voltage reference.
1 (SMD resistor) Use internal 3.3 V from the
Change to Position 3 to use an external V
