Description
Analog Ground. The voltage to this pin should be mid-way
between V and V .
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.
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.
Analog Input for Voltage. The current into the A/D converter
should be set at 14µA
voltage sense input saturates at an input current of ±25µA peak.
Inputs for current sensor. The shunt resistor voltage from each
channel is converted to a current of 16µA
The current sense input saturates at an input current of ±25µA
peak.
This pin provides the connection for the reference current setting
resistor. A 24k resistor connected to V set the optimum
operating condition.
Pulse rate output. Refer to pulse output format for a description
of the pulse rate.
Leave pins unconnected.
