PF
Notes: 1. Specifications guaranteed by design and characterization.
2. Active energy is tested with power factor (PF) = 1.0. Reactive energy is tested with Sin() = 1.0. Energy error measured at system
level using a single energy pulse. Where: 1) One energy pulse = 0.5Wh or 0.5Varh; 2) VDDA = +3.3V, TA = 25°C, MCLK =
4.096MHz; 3) System is calibrated.
3. Calculated using register values; N≥4000.
4. IRMS error calculated using register values. 1) VDDA = +3.3V; TA = 25°C; MCLK = 4.096MHz; 2) AC offset calibration applied.
TYPICAL LOAD PERFORMANCE
• Energy error measured at system level using single energy pulse; where one energy pulse = 0.5Wh or 0.5Varh.
• IRMS error calculated using register values.
• VDDA = +3.3V; TA = 25°C; MCLK = 4.096MHz.
