ORDERING INFORMATION

PIN DESCRIPTION

Analog Ground. The voltage to this pin should be mid-way between V

and V .

DD

SS

Positive supply voltage. Typically +5V if a current transformer is used for current sensing.

GND

Voltage sense inputs. The current into the A/D converter should be set at 14µA

at nominal mains

RMS

voltage. The voltage sense input saturates at an input current of ±25µA peak.

IVN1, IVN2,

IVN3

Inputs for current sensors. The termination resistor voltage from each current transformer is

converted to a current of 16µA

at rated conditions. The current sense input saturates at an input

RMS

current of ±25µA peak.

This pin provides the connection for the reference current setting resistor. A 24kW resistor

connected to V sets the optimum operating condition.
