Default Position Function
JP3
A
Use JP3 to select the V
DRIVE
source for the AD7606C-18.
In Position A, the AD7606C-18 is supplied with 3.3 V from the
In Position B, the AD7606C-18 is supplied with 3.3 V from the
JP4
A
The
software controls the RANGE pin. If using the EVAL-AD7606C18FMCZ in standalone mode, JP4
allows the selection of the analog input range in hardware mode. In this case, change the R20 resistor to a
0 Ω link.
In Position A, the RANGE pin is tied to V
DRIVE
, and the ±10 V range is selected.
In Position B, the RANGE pin is tied to AGND, and the ±5 V range is selected.
In software mode, the RANGE pin is ignored.
JP5
A
The ACE software controls the PAR/SER SEL pin. If using the EVAL-AD7606C18FMCZ in standalone mode,
JP5 allows the selection of the digital interface. In this case, change the R19 and R21 resistors to 0 Ω links
In Position A, the PAR/SER SEL pin is tied to V
DRIVE
, and the serial interface is selected.
In Position B, the PAR/SER SEL pin is tied to AGND, and the parallel interface is selected.
JP6
A
The ACE software controls the REF SELECT pin. By default, the internal reference is selected. If switching to
the external reference is required through the ACE software, P5 must be inserted. If using the EVAL-
AD7606C18FMCZ in standalone mode, JP6 allows the selection of the reference. In this case, change the
R13 resistor to a 0 Ω link.
In Position A, the REF SELECT pin is tied to V
DRIVE
, and the internal reference is enabled and selected. P5
must be unpopulated.
In Position B, the REF SELECT pin is tied to AGND, the internal reference is disabled, and the external
reference is selected. P5 must be inserted if using the on-board U1 devices, and must not be inserted if
using the J9 SMB connector.
JP7
B
JP7 selects the V1− line to be connected to ground (single-ended operation) or to the SMB connector
(differential operation).
Position A connects the V1− line to ground for single-ended operation.
Position B connects the V1− line to the J5 SMB connector and disconnects the V1− line from ground.
JP8, JP10
A
Position A bypasses the amplifier mezzanine card (AMC).
Position B enables the AMC to be connected on the P7 and P11 headers.
JP9, JP11
A
Position A bypasses the AMC.
Position B enables the AMC to be connected on the P7 and P11 headers.
JP12
B
JP12 selects the V2− line to be connected to ground (single-ended operation) or to the SMB connector
(differential operation).
Position A connects the V2− line to ground for single-ended operation.
Position B connects the V2− line to the J6 SMB connector and disconnects the V2− line from ground.
JP13
B
JP13 selects the V3− line to be connected to ground (single-ended operation) or to the SMB connector
(differential operation).
Position A connects the V3− line to ground for single-ended operation.
Position B connects the V3− line to the J7 SMB connector and disconnects the V3− line from ground.
JP14
B
JP14 selects the V4− line to be connected to ground (single-ended operation) or to the SMB connector
(differential operation).
Position A connects the V4− line to ground for single-ended operation.
Position B connects the V4− line to the J8 SMB connector and disconnects the V4− line from ground.
P13
Not inserted
Inserting P13 connects the V5− line to ground.
P14
Not inserted
Inserting P14 connects the V8− line to ground.
P15
Not inserted
Inserting P15 connects the V6− line to ground.
P16
Not inserted
Inserting P16 connects the V7− line to ground.
S1
Open
The ACE software controls the OS0, OS1, and OS2 pins. If using the EVAL-AD7606C18FMCZ in standalone
mode, these switches select the logic level on the OS0, OS1, and OS2 pins.
