Measurement error = (Energy Measured By Device - True Energy)/True Energy * 100%. Accuracy is
measured with signal (±660 mV) on Channel 1. F
See typical performance curves for higher frequencies and increased dynamic range. This parameter is
not 100% production tested.
Does not include internal V
measured output frequency and expected transfer function.
Percent of HF
CH2 = 100 mV
Error applies down to 60 degree lead (PF = 0.5 capacitive) and 60 degree lag (PF = 0.5 inductive).
Refer to Section 4.0 “Device Overview” for complete description.
Specified by characterization, not production tested.
1 MCLK period at 3.58 MHz is equivalent to less than < 0.005 degrees at 50 or 60 Hz.
