Description

AGND

16

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

VDD

6

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

AGND.

VSS

14

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

AGND.

IVP1, IVP2,

IVP3

17, 20, 3

Analog Inputs for Voltages. The maximum current into the voltage sense inputs IVP should

not exceed

voltage sense inputs saturate at an

input current of ±25μA peak.
