3	AGND	power_in	Analog ground.
4	IBP	input	Phase B current sampling channel positive analog input; fully differential input with maximum peak-to-peak difference 800mVp.
5	IBN	input	Phase B current sampling channel negative analog input; fully differential input with maximum peak-to-peak difference 800mVp.
6	AVCC	power_in	Analog +3.3V power supply, operating range 3.0V-3.6V; decouple with 10µF capacitor in parallel with 0.1µF capacitor to analog ground.
7	ICP	input	Phase C current sampling channel positive analog input; fully differential input with maximum peak-to-peak difference 800mVp.
8	ICN	input	Phase C current sampling channel negative analog input; fully differential input with maximum peak-to-peak difference 800mVp.
9	VAP	input	Phase A voltage sampling channel positive analog input; fully differential input with maximum peak-to-peak difference 800mVp.
10	VAN	input	Phase A voltage sampling channel negative analog input; fully differential input with maximum peak-to-peak difference 800mVp.
11	VBP	input	Phase B voltage sampling channel positive analog input; fully differential input with maximum peak-to-peak difference 800mVp.
12	VBN	input	Phase B voltage sampling channel negative analog input; fully differential input with maximum peak-to-peak difference 800mVp.
13	VCP	input	Phase C voltage sampling channel positive analog input; fully differential input with maximum peak-to-peak difference 800mVp.
14	VCN	input	Phase C voltage sampling channel negative analog input; fully differential input with maximum peak-to-peak difference 800mVp.
15	INP	input	Neutral line current sampling channel positive analog input; fully differential input with maximum peak-to-peak difference 800mVp.
16	INN	input	Neutral line current sampling channel negative analog input; fully differential input with maximum peak-to-peak difference 800mVp.
17	CF3	output	Energy calibration pulse output; configurable via CFCFG register for fundamental/full-wave or active/reactive/apparent energy pulse output.
18	CF2	output	Energy calibration pulse output; configurable via CFCFG register for fundamental/full-wave or active/reactive/apparent energy pulse output.
