8 / 56 page CS5490 8 DS982F2 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.
