CONNECTING THE EVALUATION BOARD
Figure 4 shows a picture of the E VA L -ADE7169EBZ-2/
ADE5169EBZ-2 board with the communication and power
ports highlighted.
POWER SUPPLIES AND LOAD
Power can be supplied to the EVAL-ADE7169EBZ-2/
ADE5169EBZ-2 board by using the 9 V dc power adaptor that
is supplied with the evaluation kit. Connect the power jack to
the on-board connector shown in Figure 4. Next, insert the plug
into a 220 V or 110 V mains wall socket to provide power.
Refer to the Analog Inputs (P3 and P11) section for instructions
on how to connect the current and voltage signals to the chip,
and note the safety instructions (see the Safety section).
COMMUNICATIONS
Communication with the PC can be achieved using the USB-to-
UART converter (ADE8052Z-DWDL1). This USB-to-UART
board is isolated and, therefore, safe to connect directly to the
PC even if the ground of the evaluation board is tied to 220 V,
as is the case when a shunt is used as the current sensor.
However, caution must be used (see the Safety section). The
location of these connectors is shown in Figure 4. Connect the
other end of the cable to a USB port on the PC. Prior to using
the USB-to-UART board, the driver must be installed. See the
Installing the Drivers section for full details on the installation
procedure.
SAFETY
Exercise caution when connecting current or voltage sensors
directly to the 220 V mains supply because the ground of the
E VA L-ADE7169EBZ-2/ADE5169EBZ-2 may become live, thus
creating the potential for electric shock. It is recommended to
use an isolation transformer when working with the mains for
safety reasons. Note that if an external dc supply is used with an
isolation transformer on the mains, then the ground of the dc
supply must not be connected to earth ground. If this condition
occurs, then the isolation in the isolation transformer is bypassed.
The mains should not be energized before verifying the connec-
tion of the analog inputs is correct (see Figure 5 to Figure 9 in
the Analog Inputs (P3 and P11) section), according to the current
sensor type. In addition, JP4 on the voltage input should be
verified to be open before using the mains connection to prevent
damage to the IC. If connecting the board to external equipment
such as a PC, ensure that the communication channel is isolated
using the USB-to-UART converter. The evaluation board and
communication boards should not be handled when the supply
is connected.

ANALOG INPUTS (P3 AND P11)
Voltage and current signals are connected at the screw terminal, at
P3 and P11, respectively. All analog input signals are filtered
using the on-board antialias filters before being presented to the
analog inputs of the energy metering IC.
CURRENT SENSE INPUTS (P11)
P11 is a three-way connection block that allows the ADE71xx/
ADE75xx/ADE51xx/ADE55xx to be connected to a current
transducer.
The RC networks are the antialias filters that are required by the
on-chip ADCs. The default corner frequency for these low-pass
filters (LPFs) is selected as 4.8 kHz with a resistor of 1 kΩ and a
capacitor of 33 nF).

USING A CT AS THE CURRENT TRANSDUCER
Figure 5 shows how a current transformer (CT) can be used as a
current transducer in a single-phase, 2-wire distribution system.
The CT secondary current is converted to a voltage by using a
burden resistance across the secondary winding outputs. Care
should be taken when using a CT as the current transducer. If
the secondary is left open, that is, no burden is connected, a
large voltage may be present at the secondary outputs. This can
cause an electrical shock hazard and potentially damage
electronic components.
When using a CT as the current sensor, the antialias filters
should be enabled by opening Jumper JP19 and Jumper JP1
(see Figure 8).
Most CTs have an associated phase shift of between 0.1° and 1°
at 50 Hz/60 Hz. This phase shift or phase error can lead to signifi-
cant energy measurement errors, especially at low power factors.
However, this phase error can be corrected by writing to the
phase calibration register (PHCAL[7:0]) in the ADE7169/
ADE5169. The software supplied with the ADE7169/ADE5169
evaluation board allows user adjustment of the phase calibra-
tion register. See the Evaluation Board Software section for
more information.
The maximum analog input range and gain for the current and
voltage channels are set via the gain register (see the respective
data sheet). The evaluation software allows the user to configure
the channel range and gain. This means that the maximum
peak differential signal on Channel 1 is 0.5 V (at gain = 1).
For an antitamper configuration, measuring both the phase and
neutral currents, two CTs can be used as shown in Figure 6. Other
antitamper current sensor options include one shunt and one
CT, as shown in Figure 7.

USING A SHUNT RESISTOR AS THE CURRENT
TRANSDUCER
Figure 8 shows how a shunt resistor can be used to perform
the current-to-voltage conversion required for the ADE71xx/
ADE75xx/ADE51xx/ADE55xx. A shunt is a very cost effective
way to sense current in a 2-wire, single-phase application. Isola-
tion is not typically required in a 2-wire application and the
shunt has advantages over the CT arrangement. For example, a
shunt does not suffer from dc saturation problems and the
phase response of the shunt is linear over a very wide dynamic
range. Although the shunt is predominately resistive, it does
have parasitic reactive elements (inductance) that can become
significant, even at 50 Hz/60 Hz. This means that there can be a
small phase shift associated with the shunt. However, the phase
shift is easily compensated by writing to the phase calibration
register (PHCAL[7:0]) in the ADE71xx/ADE75xx/ADE51xx/
ADE55xx.
Figure 8 shows how the shunt can be connected to the evalua-
tion board. Two sense wires should be soldered to the shunt at
the copper/manganium junctions as shown. These sense wires
should be formed into a twisted pair to reduce the loop area,
which in turn reduces antenna effects. A connection for the
common-mode voltage can be made at the connection point for
the current-carrying conductor.
For an antitamper configuration, measuring both the phase and
neutral currents, two CTs can be used, as shown in Figure 6. Other
antitamper current sensor options include one shunt and one
CT, shown in Figure 7.
It is not possible to use two shunt resistors as current sensors for
use in an antitamper configuration with the ADE71xx/ADE51xx
products because, with a shunt resistor, the line or the neutral is
used as a ground reference for the ADE71xx/ADE51xx IC.
There is no isolation between the two current channels in the
ADE71xx/ADE51xx, and the line and neutral would be effec-
tively shorted together, which is dangerous.

Voltage Sense Inputs
The voltage input connections on the ADE71xx/ADE75xx/
ADE51xx/ADE55xx evaluation board can be connected directly
to the line voltage source. However, an isolation transformer is
recommended for safety reasons. The line voltage is attenuated
using a simple resistor divider network before it is presented to the
ADE71xx/ADE75xx/ADE51xx/ADE55xx. The voltage channel
is recommended to be used in a single-ended configuration.
Figure 9 shows a typical connection for the line voltage.
Note that the analog input VN is connected to AGND via the
antialias filter R14/C15. Jumper JP9 should be left open.
The voltage attenuation network is made up of R12, R13, and
R15. The maximum signal level permissible at VP is 0.5 V peak.
The signal range should not exceed ±0.5 V with respect to
AGND for specified operation.
The attenuation network can be easily modified by the user to
accommodate any input signal level. However, the value of R15
(1 kΩ) should not be altered because the phase response of
Channel 2 should match that of Channel 1.
