external reference voltage input and NXC-VAI4 power supply GND.

External reference input:

 

• Maximum external reference input voltage = +12 VDC.

(EREF - one for each output)

Over-voltage protection to +28 VDC.

 

Internal reference output:

 

• +5 V reference output, maximum current = 60 mA.

(IREF)

• This output is intended to drive a ground-referenced load.
