XOUT, XIN - A single stage amplifier inside the chip is connected to these pins and can be used
with a crystal to provide the system clock for the device. Alternatively, an external clock can be
supplied to the XIN pin to provide the system clock for the device.
CPUCLK - Output of on-chip oscillator which can drive one standard CMOS load.
IGAIN1, IGAIN0 - Used to select the current channel input gain range.
FREQ2,FREQ1,FREQ0 - Used to select max pulse output frequency for E1, E2, and FOUT.
HPF - High disables the HPF. Low activates HPF on Voltage channel. Connecting HPF pin to
FOUT pin activates HPF on Current channel.
RESET - Low activates Reset.
E1, E2 - Active low alternating pulses with an output frequency that is proportional to the active
(real) power.
FOUT - Outputs energy pulses at a frequency higher than E1 and E2 outputs. Used for calibra-
tion purposes.
NEG - High indicates negative energy.
VIN+, VIN- - Differential analog input pins for voltage channel.
VREFOUT - The on-chip voltage reference output pin. The voltage reference has a nominal
magnitude of 2.5 V and is referenced to the AGND pin on the converter.
VREFIN - Voltage input to this pin establishes the voltage reference for the on-chip modulators.
IIN+, IIN- - Differential analog input pins for current channel.
VD+ - The positive digital supply.
DGND - Digital Ground.
AGND - Analog Ground.
VA+ - The positive analog supply.
