PIN CONFIGURATION AND FUNCTION DESCRIPTIONS
NOTES
1. NC = NO CONNECT. THESE PINS ARE NOT CONNECTED
INTERNALLY AND SHOULD BE LEFT FLOATING.
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. CONNECT THE PAD
S
TO AGND AND DGND.

Pin No. Mnemonic Description
1, 10, 11, 20,
21, 30, 31, 40
NC No Connect. These pins are not connected internally and should be left floating.
33, 34 NC No Connect. These pins should be left floating. Do not connect to GND.
2 PULL_HIGH Connect this pin to VDD for proper operation.
3 PULL_LOW Connect this pin to AGND for proper operation.
4
AARESET
EE
Active Low Reset Input. Hold this pin low for at least 10 μs to trigger a hardware reset.
5 DVDD
On-Chip 2.5 V Digital LDO Access. 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. Connect these inputs in a single-ended configuration with a maximum
signal level of ±0.5 V with respect to IAN.
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. Connect these inputs in a single-ended configuration with a maximum
signal level of ±0.5 V with respect to IBN.
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. Connect these inputs in a single-ended configuration with a maximum
signal level of ±0.5 V with respect to ICN.
15, 16 VP, VN
Analog Inputs for the Voltage Channel. This channel is used with the voltage transducer and is referenced as
the voltage channel in this data sheet. Connect these inputs in a single-ended configuration with a maximum
signal level of ±0.5 V with respect to VN. This channel also has an internal PGA.
17 REF
IN/OUT
On-Chip Voltage Reference Access. 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.
18 IN
Analog Input Common Pin for Current Channel D, Current Channel E, and Current Channel F. See the pin
descriptions for Pin 19, Pin 22, and Pin 23 for more details.
19 IFP
Analog Input for Current Channel F. This channel is used with the current transducers and is referenced in this
data sheet as Current Channel F. Connect this input in a single-ended configuration with a maximum signal
level of ±0.5 V with respect to IN.
22 IEP
Analog Input for Current Channel E. This channel is used with the current transducers and is referenced in
this data sheet as Current Channel E. Connect this input in a single-ended configuration with a maximum
signal level of ±0.5 V with respect to IN.
23 IDP
Analog Input for Current Channel D. This channel is used with the current transducers and is referenced in
