Description
1DVDD
Digital Power Supply. This pin provides the supply voltage for the digital circuitry in the ADE7751.
The supply voltage should be maintained at 5 V
± 5% for specified operation. This pin should be
decoupled with a 10
µF capacitor in parallel with a ceramic 100 nF capacitor.
2
AC/
DC
High-Pass Filter Select. This logic input is used to enable the HPF in Channel 1 (the current
channel). A Logic 1 on this pin enables the HPF. The associated phase response of this filter has
been internally compensated over a frequency range of 45 Hz to 1 kHz. The HPF filter should be
enabled in energy metering applications.
3AVDD
Analog Power Supply. This pin provides the supply voltage for the analog circuitry in the ADE7751.
The supply should be maintained at 5 V
± 5% for specified operation. Every effort should be made
to minimize power supply ripple and noise at this pin by the use of proper decoupling. This pin
should be decoupled to AGND with a 10
µF capacitor in parallel with a ceramic 100 nF capacitor.
4, 5
V1A, V1B
Analog Inputs for Channel 1 (Current Channel). These inputs are fully differential voltage inputs
with a maximum signal level of
±660 mV with respect to pin V1N for specified operation. The
maximum signal level at these pins is
±1 V with respect to AGND. Both inputs have internal ESD
protection circuitry and an overvoltage of
±6 V can also be sustained on these inputs without risk of
permanent damage.
6
V1N
Negative Input Pin for Differential Voltage Inputs V1A and V1B. The maximum signal level at this
pin is
±1 V with respect to AGND. The input has internal ESD protection circuitry and an overvoltage
of
±6 V can also be sustained without risk of permanent damage. This input should be directly con-
nected to the burden resistor and held at a fixed potential, i.e., AGND. See Analog Input section.
7, 8
V2N, V2P
Negative and Positive Inputs for Channel 2 (Voltage Channel). These inputs provide a fully differ-
ential input pair. The maximum differential input voltage is
±660 mV for specified operation. The
maximum signal level at these pins is
±1 V with respect to AGND. Both inputs have internal ESD
protection circuitry and an overvoltage of
±6 V can also be sustained on these inputs without risk of
permanent damage.
9
RESET
Reset Pin for the ADE7751. A logic low on this pin will hold the ADCs and digital circuitry in a
reset condition. Bringing this pin logic low will clear the ADE7751 internal registers.
10
REFIN/OUT
Provides Access to the On-Chip Voltage Reference. The on-chip reference has a nominal value of
2.5 V
± 8% and a typical temperature coefficient of 30 ppm/°C. An external reference source may also
be connected at this pin. In either case, this pin should be decoupled to AGND with a 1
µF ceramic
capacitor and 100 nF ceramic capacitor.
11
AGND
Provides the Ground Reference for the Analog Circuitry in the ADE7751, i.e., ADCs and Refer-
ence. This pin should be tied to the analog ground plane of the PCB. The analog ground plane is
the ground reference for all analog circuitry, e.g., antialiasing filters, current and voltage trans-
ducers, and more. For good noise suppression, the analog ground plane should only be connected to
the digital ground plane at one point. A star ground configuration will help to keep noisy digital
return currents away from the analog circuits.
12
SCF
Select Calibration Frequency. This logic input is used to select the frequency on the calibration
output CF. Table IV shows how the calibration frequencies are selected.
