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

1000 to 1 @ 25°C
Ultralow battery supply current: 1.7 μA
Selectable output frequency: 1 Hz to 16 kHz
Embedded digital crystal frequency compensation for
calibration and temperature variation of 2 ppm resolution
Integrated LCD driver
108-segment driver for the ADE5566 and ADE5569
104-segment driver for the ADE5166 and ADE5169
2×, 3×, or 4× multiplexing
4 LCD memory banks for screen scrolling
LCD voltages generated internally or with external resistors
Internal adjustable drive voltages up to 5 V independent
of power supply level
<0.5% error on reactive energy over a dynamic range of
1000 to 1 @ 25°C (ADE5169 and ADE5569 only)
<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
