ENERGY MEASUREMENT FEATURES
Proprietary analog-to-digital converters (ADCs) and digital
signal processing (DSP) provide high accuracy active
(Watt), reactive (VAR), and apparent energy (VA)
measurement

range of 1000 to 1 @ 25°C
Less than 0.5% error on reactive energy over a dynamic
range of 1000 to 1 @ 25°C (ADE7569 and ADE7169 only)
Less than 0.5% error on root  mean square (rms)
measurements over a dynamic range of 500 to 1 for
current (Irms) and 100 to 1 for voltage (Vrms) @ 25°C
