Datasheet ADE9153A (Analog Devices)

Energy Metering IC with Autocalibration Data Sheet ADE9153A FEATURES GENERAL DESCRIPTION m Sure autocalibration
The ADE9153A1 is a highly accurate, single-phase, energy metering
Automatic calibration based on a direct measurement of
IC with autocalibration. The mSure® autocalibration feature allows
the full signal path
a meter to automatically calibrate the current and voltage channels
Calibration procedure not requiring a reference meter
without using an accurate source or an accurate reference meter
m Sure autocalibration Class 1 meter guaranteed
when a shunt resistor is used as a current sensor. Class 1 and
3 high performance ADCs
Class 2 meters are supported by mSure autocalibration.
88 dB SNR
The ADE9153A incorporates three high performance analog-
High gain current channel: ±26.04 mV peak, 18.4 mV rms
to-digital converters (ADCs), providing an 88 dB signal-to-noise
input at highest gain setting
ratio (SNR). The ADE9153A offers an advanced metrology feature
Advanced metrology feature set
set of measurements like line voltage and current, active energy,
WATT, VAR, VA, Wh, VARh, and VAh
