Description
Disables the antialiasing filter (composed of R11 and C13) in the IBP signal path.
Enables the antialiasing filter (composed of R11 and C13) in the IBP signal path.
Disables the antialiasing filter (composed of R10 and C12) in the IAN signal path.
Enables the antialiasing filter (composed of R10 and C12) in the IAN signal path.
Disables the antialiasing filter (composed of R12 and C14) in the IBN signal path.
Enables the antialiasing filter (composed of R12 and C14) in the IBN signal path.
Connects Pin 1 of the Channel V pin connector (P4) to AGND. Use this configuration in conjunction with JP8A
closed to connect the VP pin of the ADE7953 to AGND via 1 kΩ Resistor R15.
Pin 1 of the Channel V pin connector (P4) is left floating. Use this configuration in normal operation to drive VP
with analog signal.
Disables the 1000:1 attenuator network (composed of R13, R14, R15, and R17) when JP8B is open. Use this
configuration when using a low voltage signal source on the voltage channel.
Enables the 1000:1 attenuator network (composed of R13, R14, R15, and R17) when JP8B is closed. Use this
configuration when using a high voltage signal source on the voltage channel.
Enables the 1000:1 attenuator network (composed of R13, R14, R15, and R17) when JP8A is open. Use this
configuration when using a high voltage signal source on the voltage channel.
Disables the 1000:1 attenuator network (composed of R13, R14, R15, and R17) when JP8A is closed. Use this
configuration when using a low voltage signal source on the voltage channel.
Connects Pin 2 of the Channel V pin connector (P4) to AGND. Use this configuration to connect the VN pin of the
ADE7953 to AGND via 1 kΩ Resistor R16, which should be done when normal single-ended signals are connected
to the ADE7953 voltage channel.
Pin 2 of the Channel V pin connector (P4) is left floating. Use this configuration to drive VN with a differential signal.
Connects the ADR280 voltage reference to the REF pin of the ADE7953. Use this configuration when the ADE7953
is configured to use an external reference.
Disconnects the ADR280 voltage reference from the REF pin of the ADE7953. Use this configuration in normal
operation when the ADE7953 is configured to use the internal reference.
Connects Pin 1 of the on-board 3.579545 MHz Crystal Y1 to the CLKIN pin of the ADE7953. Use this configuration
when External Crystal Y1 is used as the clock source for the ADE7953.
Disconnects Pin 1 of the on-board 3.579545 MHz Crystal Y1 from the CLKIN pin of the ADE7953. Use this configu-
ration when an external clock is used. This clock can be connected to Pin 6 of 16×1 Header P5.
Connects the externally applied 3.3 V power to ADuM1401 Isolator U2. Use this configuration in normal operation
when communicating with the ADE7953 via the interface board.
Disconnects the externally applied 3.3 V power to ADuM1401 Isolator U2. Use this configuration when isolation
and/or communication is not required with the ADE7953.
Connects the externally applied 3.3 V power to ADuM1401 Isolator U3. Use this configuration in normal operation
when communicating with the ADE7953 via the interface board.
Disconnects the externally applied 3.3 V power to ADuM1401 Isolator U3. Use this configuration when isolation
and/or communication is not required with the ADE7953.
Connects the externally applied 3.3 V power to ADuM1401 Isolator U4. Use this configuration in normal operation
when communicating with the ADE7953 via the interface board.
Disconnects the externally applied 3.3 V power to ADuM1401 Isolator U4. Use this configuration when isolation
and/or communication is not required with the ADE7953.
Connects the externally applied 3.3 V power to ADuM1401 Isolator U5. Use this configuration in normal operation
when communicating with the ADE7953 via the interface board.
Disconnects the externally applied 3.3 V power to ADuM1401 Isolator U5. Use this configuration when isolation
and/or communication is not required with the ADE7953.
Connects the externally applied 3.3 V power to the ADuM1250 bidirectional isolator, U6. Use this configuration
when communicating with the ADE7953 via the interface board using I²C.
Disconnects the externally applied 3.3 V power to the ADuM1250 bidirectional isolator, U6. Use this configuration
when isolation and/or I²C communication is not required with the ADE7953.
