Read Input. RD controls conversions and
data access. See Digital Interface section.
Interrupt Output. INT going low indi-
cates the completion of a conversion.
See Digital Interface section.
Ground
Lower Limit of Reference Span. Sets
the zero-code voltage.
Range: GND to V
Upper Limit of Reference Span. Sets
the full-scale input voltage.
Range: V
Ready Output. Open-drain output with
no active pull-up device. Goes low
when CS goes low and high imped-
ance at the end of a conversion.
Chip-Select Input. CS must be low for
the device to be selected.
