On-Board Connectors
Table 2 provides information about the external connectors on the EVAL-AD7124-4SDZ .
Table 2. On-Board Connectors
Connector Function
J1 A 120-pin connector that mates with the EVAL-SDP-CB1Z (controller board).
J2 Straight PCB mount SMB/SMA jack for master clock (not inserted). The EVAL-AD7124-4SDZ has the footprint to include an
SMA/SMB connector, if an external clock source is being used to provide the master clock to the ADC.
J3 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.
J6 Analog input connector. Connections to AIN0 to AIN5 are available along with REFIN1(±) connections. This connector can be
used to connect an RTD to the
AD7124-4 .
J9 Optional external connector, allowing external bench top or alternative supply for AV
DD
and IOV
DD
. When split supplies are
used, AV
SS
is supplied externally via J9.
J11 Analog input connector. Connections to AIN6 to AIN7 are available along with REFIN1(±) and analog power supply connections.
This connector can be used to connect a load cell to the
AD7124-4 .
J12 6-pin connector. Provides an I 2 C interface to allow the SDP to interface to a digital temperature sensor. This is required if a
thermocouple is interfaced to the AD7124-4 using Connector A2.
J13 7-pin connector that can be used to connect an external amplifier to Channel AIN4/Channel AIN5.
J14 7-pin connector that allows connection to the AIN4 and AIN5 pins.
A0 Straight PCB mount SMB/SMA jack. The footprint for an SMA/SMB connector is included on the evaluation board to provide
the signal to the AIN4 analog input.
A1 Straight PCB mount SMB/SMA jack. The footprint for an SMA/SMB connector is included on the evaluation board to provide
the signal to the AIN5 analog input.
A2 Thermocouple connector. This connector is required if a thermocouple is being interfaced to the evaluation board.
A5 Straight PCB mount SMB/SMA jack. The footprint for an SMA/SMB connector is included on the evaluation board to provide
the ) signal.
A6 Straight PCB mount SMB/SMA jack. The footprint for an SMA/SMB connector is included on the evaluation board to provide
the REFIN1(−) signal.
