Supply Inputs

VA1+, VA2+ — Positive Analog Supply

Input for positive analog supply is +5 V typical when AGND is 0 V.

AGND — Analog Ground

Analog ground for circuits supplied by VA+.

VD1+, VD2+ — Positive Digital Supply

Input for positive digital supply is +5 V typical when DGND is 0 V.

DGND — Digital Ground

Digital ground for circuits supplied by VD+.

Signal and Reference Related Inputs

AIN+, AIN- — Differential Analog Inputs

Fully differential signal inputs.

VREFIN — Voltage Reference Input

VREFOUT or an external reference is connected to VREFIN. Analog input voltage (full scale

fully differential peak-to-peak) into the converter is 1.6 times this value.
