mance. Amplifiers that have been used successfully to drive

the analog inputs of the ADC16061 include the CLC427,

CLC440, LM6152, LM6154, LM6181 and the LM6182. A

small series reistor at each amplifier output and a capacitor

across the analog inputs (as shown in

Figure 7

) will often im-

prove performance.

Operating with the reference pins outside of the speci-

fied range. As mentioned in section 1.2, V

REF

should be in

the range of

1.8V ≤ V

REF

≤ 2.2V

with V

REF

−

≤ 1.0V. Operating outside of these limits could

lead to excessive distortion or noise.

Using a clock source with excessive jitter, using an ex-

cessively long clock signal trace, or having other sig-

nals coupled to the clock signal trace. This will cause the

sampling interval to vary, causing excessive output noise

and a reduction in SNR performance.

Connecting pins marked ″NC″ to any potential. Some of

these pins are used for factory testing. They should all be left

floating. Connecting them to ground, power supply, or some

other voltage could result in a non-functional device.
