CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate
on the human body and test equipment and can discharge without detection. Although the ADSST-
EM-2030 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended
to avoid performance degradation or loss of functionality.

Logic Channels Output for
Multiplexer to Switch Gain for
A-Phase Current
Logic Channels Output for
Multiplexer to Switch Gain for
B-Phase Current
Logic Output Indicating that One
More Current Is Reversed
Calibration Frequency Logic Output.
This gives instantaneous real power
information and can be used for
calibration.
Logic Channels Output for
Multiplexer to Switch Gain for
C-Phase Current
Low Frequency Logic Outputs. F1
and F2 provide average real power
information. The logic outputs can
be used to drive electromechanical
counters and 2-phase stepper motors.

This Logic Signal conveys to ADSST-
EM-2030 that data transfer on SPI is
requested.
Data Output on SPI from
ADSST-EM-2030
Clock for SPI. This clock is generated
by an external microcontroller when
the data transfer to or from ADSST-
EM-2030 takes place.
