GENERAL DESCRIPTION
The ADE9153A
1
is a highly accurate, single-phase, energy metering
IC with autocalibration. The mSure® autocalibration feature allows
a meter to automatically calibrate the current and voltage channels
without using an accurate source or an accurate reference meter
when a shunt resistor is used as a current sensor. Class 1 and
Class 2 meters are supported by mSure autocalibration.
The ADE9153A incorporates three high performance analog-
to-digital converters (ADCs), providing an 88 dB signal-to-noise
ratio (SNR). The ADE9153A offers an advanced metrology feature
set of measurements like line voltage and current, active energy,
fundamental reactive energy, and apparent energy calculations,
and current and voltage rms calculations. ADE9153A includes
power quality measurements such as zero crossing detection, line
period calculation, angle measurement, dip and swell, peak and
overcurrent detection, and power factor measurements. Each input
channel supports independent and flexible gain stages. Current
Channel A is ideal for shunts, having a flexible gain stage and
providing full-scale input ranges from 62.5 mV peak down to
26.04 mV peak. Current Channel B has gain stages of 1×, 2×,
and 4× for use with current transformers (CTs). A high speed,
10 MHz, serial peripheral interface (SPI) port allows access to
the ADE9153A registers.
Note that throughout this data sheet, multifunction pins, such
as ZX/DREADY/CF2, are referred to either by the entire pin
name or by a single function of the pin, for example, CF2, when
only that function is relevant.
The ADE9153A operates from a 3.3 V supply and is available in
a 32-lead LFCSP package.
