PIN DESCRIPTION
Clock Generator
Crystal Out
Crystal In
1, 24
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.
CPU Clock Output
2
CPUCLK - Output of on-chip oscillator which can drive one standard CMOS load.
Control Pins
Gain Select
5, 7
IGAIN1, IGAIN0 - Used to select the current channel input gain range.
Frequency Select
17, 20, 23 FREQ2,FREQ1,FREQ0 - Used to select max pulse output frequency for E1, E2, and FOUT.
High Pass Filter Enable
8
HPF - High disables the HPF. Low activates HPF on Voltage channel. Connecting HPF pin to
FOUT pin activates HPF on Current channel.
Reset
19
RESET - Low activates Reset.
Energy Pulse Outputs
Energy Output
22, 21
E1, E2 - Active low alternating pulses with an output frequency that is proportional to the active
(real) power.
High Freq Output
18
FOUT - Outputs energy pulses at a frequency higher than E1 and E2 outputs. Used for calibra-
tion purposes.
Neg Energy Indicator
6
NEG - High indicates negative energy.
Analog Inputs/Outputs
Differential Voltage Inputs
9, 10
VIN+, VIN- - Differential analog input pins for voltage channel.
Voltage Reference
Output
11
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.
Voltage Reference Input
12
VREFIN - Voltage input to this pin establishes the voltage reference for the on-chip modulators.
Differential Current Inputs
16, 15
IIN+, IIN- - Differential analog input pins for current channel.
Power Supply Connections
Positive Digital Supply
3
VD+ - The positive digital supply.
Digital Ground
