On-Board Connectors
Table 2 provides information about the external connectors on the EVAL-AD7124-8SDZ.
Table 2. On-Board Connectors
Connector
Function
J1
A 120-pin connector that mates with the
(black colored controller board).
J2
Straight PCB Mount SMB/SMA Jack for master clock (not inserted). The EVAL-AD7124-8SDZ 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 ) connections.
This connector can be used to connect an RTD to the AD7124-8.
J9
Optional external connector, allowing external bench top or alternative supply for AVDD and IOVDD.
When split supplies are used, AVSS is supplied externally via J9.
J11
Analog input connector. Connections to AIN6 to AIN7 are available along with ) and analog
power supply connections. This connector can be used to connect a loadcell to the AD7124-8.
J12
6-pin connector. Provides an I2C interface to allow the SDP to interface to a digital temperature sensor.
This is required if a thermocouple is interfaced to the AD7124-8 using connector A2.
J13
7-pin connector which can be used to connect an external amplifier to channel AIN4/AIN5.
J14
7-pin connector which allows connection to pins AIN4 and AIN5.
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 analog input AIN4.
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 analog input AIN5.
A2
Thermocouple connector. This connector is required useful 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 signal REFIN1(-).
