VIN+, VIN- - Differential analog input pins for voltage channel.

VREFOUT - The on-chip voltage reference is output from this pin. The voltage reference has a

nominal magnitude of 2. 5V and is referenced to the AGND pin on the converter.

VREFIN - The voltage input to this pin establishes the voltage reference for the on-chip modula-

tor.

IIN+, IIN- - Differential analog input pins for current channel.

VD+ - The positive digital supply.

DGND - Digital Ground

AGND - Analog Ground

VA+ - The positive analog supply.
