ORDERING INFORMATION
PIN DESCRIPTION
Analog Ground. The supply voltage to this pin should be mid-way between
V and V .
DD
SS
Positive Supply voltage. The voltage to this pin is typically +2.5V if a shunt
resistor is used for current sensing or in the case of a current transformer a
+5V supply can be applied.
GND
V

8
Negative Supply Voltage. The voltage to this pin is typically -2.5V if a shunt
resistor is used for current sensing or in the case of a current transformer a
0V supply can be applied.
V
SS
14
Analog Input for Voltage. The current into the A/D converter should be set at
14μA
at nominal mains voltage. The voltage sense input saturates at an
RMS
input current of ±25μA peak.
19
IVP
Inputs for current sensor. The shunt resistor voltage from each channel is
converted to a current of 16μA
at rated conditions. The current sense input
RMS
saturates at an input current of ±25μA peak.

IIN, IIP
This pin provides the connection for the reference current setting resistor.
A 24k
W
resistor connected to V
sets the optimum operating condition.

VREF
Manufacturers test pin, connect to V
for normal operation.
SS
7
TEST
Connections for a crystal or ceramic resonator. (OSC1 = input; OSC2 = Output)
10, 11
OSC1, OSC2
Serial clock in. This pin is used to stobe data in and out of the SA9903B
12
SCK
Serial data out. Data from the SA9903B is strobed out on this pin. DO is
only driven when CS is active.
13
DO
Voltage zero crossover. The FMO output generates a pulse (50% duty cycle)
on every rising edge of the mains voltage.
15
FMO
Serial data in. Data is only accepted during an active chip select (CS).
17
DI
Chip select. The CS pin is active high.
18
CS
Manufacturers Test Pins. (Leave unconnected)
