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.
