Description
2
V
IN
Single-ended analog signal input. With a 2.0V
reference voltage, input signal voltages in the range
of 0V to 2.0V will be converted. See Section 1.2.
1
V
REF
Reference voltage input. This pin should be driven
from an accurate, stable reference source in the
range of 1.8V to 2.2V and bypassed to a low-noise
ground with a monolithic ceramic capacitor,
nominally 0.01 µF. See Section 1.1.
