3. CHARACTERISTICS & SPECIFICATIONS

RECOMMENDED OPERATING CONDITIONS

POWER MEASUREMENT CHARACTERISTICS

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 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
