Driving the V
mentioned in Section 2.1, the reference voltage is intended to
be fixed to provide one of two different full-scale values (650
mV

common mode voltage from 0.8V to 1.2V by tying the V

Driving the clock input with an excessively high level
signal. The ADC input clock level should not exceed the level
described in the Operating Ratings Table or the input offset
could change.
Inadequate input clock levels. As described in Section 2.3,
insufficient input clock levels can result in poor performance.

Excessive input clock levels could result in the introduction of
an input offset.
Using a clock source with excessive jitter, using an ex-
cessively long input clock signal trace, or having other
signals coupled to the input clock signal trace. This will
cause the sampling interval to vary, causing excessive output
noise and a reduction in SNR performance.
Failure to provide adequate heat removal. As described in
Section 2.6.2, it is important to provide adequate heat removal
to ensure device reliability. This can either be done with ad-
equate air flow or the use of a simple heat sink built into the
board. The backside pad should be grounded for best perfor-
mance.
