PIN CONFIGURATION AND FUNCTION DESCRIPTIONS
NOTES
1. NC = NO CONNECT.
2. CREATE A SIMILAR PAD ON THE PCB UNDER THE
EXPOSED PAD. SOLDER THE EXPOSED PAD TO
THE PAD ON THE PCB TO CONFER MECHANICAL
STRENGTH TO THE PACKAGE. DO NOT CONNECT
THE PADS TO AGND OR DGND.

NC No Connect. Do not connect to these pins. These pins are not connected internally.
2 PM0
Power Mode Pin 0. This pin, combined with PM1, defines the power mode of the ADE7880, as
described in Table 8.
3 PM1
Power Mode Pin 1. This pin defines the power mode of the ADE7880 when combined with PM0, as
described in Table 8.
4
RESET
Reset Input, Active Low. In PSM0 mode, this pin should stay low for at least 10 µs to trigger a
hardware reset.
5 DVDD
This pin provides access to the on-chip 2.5 V digital LDO. Do not connect any external active
circuitry to this pin. Decouple this pin with a 4.7 µF capacitor in parallel with a ceramic 220 nF
capacitor.
6 DGND Ground Reference. This pin provides the ground reference for the digital circuitry.
7, 8 IAP, IAN
Analog Inputs for Current Channel A. This channel is used with the current transducers and is
referenced in this data sheet as Current Channel A. These inputs are fully differential voltage inputs
with a maximum differential level of ±0.5 V. This channel also has an internal PGA equal to the ones
on Channel B and Channel C.
9, 12 IBP, IBN
Analog Inputs for Current Channel B. This channel is used with the current transducers and is
referenced in this data sheet as Current Channel B. These inputs are fully differential voltage inputs
with a maximum differential level of ±0.5 V. This channel also has an internal PGA equal to the ones
on Channel C and Channel A.
13, 14 ICP, ICN
Analog Inputs for Current Channel C. This channel is used with the current transducers and is
referenced in this data sheet as Current Channel C. These inputs are fully differential voltage inputs
with a maximum differential level of ±0.5 V. This channel also has an internal PGA equal to the ones
on Channel A and Channel B.
15, 16 INP, INN
Analog Inputs for Neutral Current Channel N. This channel is used with the current transducers and
is referenced in this data sheet as Current Channel N. These inputs are fully differential voltage
inputs with a maximum differential level of ±0.5 V. This channel also has an internal PGA, different
from the ones found on the A, B, and C channels.
17 REF
IN/OUT
This pin provides access to the on-chip voltage reference. The on-chip reference has a nominal
value of 1.2 V. An external reference source with 1.2 V ± 8% can also be connected at this pin. In
either case, decouple this pin to AGND with a 4.7 µF capacitor in parallel with a ceramic 100 nF
capacitor. After reset, the on-chip reference is enabled.
