Description
SL9
B
With this link in Position A, the AIN2 analog input on the
AD7176-2
device is connected to Connector J8.
With this link in Position B, the analog input applied via Connector J8 is buffered using the
AD8656
before
being applied to the AIN2 pin.
With this link in Position C, the analog input path includes the
AD8475
amplifier; therefore, in conjunction
with AIN3, an attenuating single-ended to differential driver is implemented.
SL10
B
With this link in Position A, the AIN3 analog input on the
AD7176-2
device is connected to Connector J8.
With this link in Position B, the analog input applied via Connector J8 is buffered using the
AD8656
before
being applied to the AIN3 pin.
With this link in Position C, the analog input path includes the
AD8475
amplifier; therefore, in conjunction
with AIN2, an attenuating single-ended to differential driver is implemented.
SL11
B
With this link in Position A, the AIN0 analog input on the
AD7176-2
device is connected to Connector J8.
With this link in Position B, the analog input applied via Connector J8 is buffered using the
AD8656
before
being applied to the AIN0 pin.
With this link in Position C, the analog input path includes the
ADA4940-1
differential amplifier; therefore,
in conjunction with AIN1, a single-ended to differential driver is implemented.
With this link in Position D, AIN0 is connected to Header J10.
AVSS to
AGND
When these links are inserted, AVSS is tied to AGND. When AVSS is set to −2.5 V, these links must be
removed.
On-Board Connectors
Table 2 provides information about the external connectors on the
EVAL-AD7176-2SDZ
.
Table 2. On-Board Connectors
Connector
Function
J1
A 120-pin connector that mates with the
EVAL-SDP-CB1Z
(black colored controller board).
J4
Bench top power supply voltage input. Apply 7 V to 9 V and GND (0 V) to this connector to power the
evaluation board.
J5
Wall wart (dc plug) power supply voltage input. Apply 7 V to 9 V and GND (0 V) to this connector to
power the evaluation board.
J8
Main analog input connector. Connections to AIN0 to AIN4 are available, along with GND connections.
J9
Optional external connector, allowing external bench top or alternative supply for AVDD1, AVDD2, and
VIO supplies. When split supplies are used, AVSS is supplied externally via J9.
J10
A 7-pin connector that can be used to connect an external amplifier to Pin AIN0 and Pin AIN1 of the
AD7176-2
.
J13
A 7-pin connector that allows connection to Pin AIN0 and Pin AIN1 of the
AD7176-2
.
