Description

Analog Ground. This is the reference pin for the current and voltage signal sensing networks. The

supply voltage to this pin should be mid-way between VDD and VSS.

Positive Supply Voltage. The voltage to this pin should be +2.5V ± 10% with respect to AGND.

Negative Supply Voltage. The voltage to this pin should be -2.5V ± 10% with respect to AGND.

Analog Input for Voltage. The maximum current into the voltage sense input IVP should not exceed

16µARMS. At nominal voltage an input current of 14μARMS is recommended. The voltage sense

input saturates at an input current of ±25µA peak.

Analog Inputs for Current. The maximum current into the current sense inputs IIP/IIN should be

set at 16µARMS. The current sense inputs saturate at an input current of ±25µA peak.

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

connected to VSS sets the optimum operating conditions.

First pulse output. Refer to the Pulse Output Signals section for further information.

Second pulse output. Refer to the Pulse Output Signals section for further information.

Connection for crystal

Manufacturers test pin. Tie to VSS for optimum protection against transients.

No connection, leave unconnected.
