Description: scene brings higher performance and lower cost to new
markets. Figure 1 shows an example of how high speed
12-bit converters are becoming affordable for the first
time to a new range of applications. At the same time, the
new converters achieve better dynamic performance with
high frequency input signals. This means that more system
designers are facing the challenge of using high
performance ADCs. In this article, we will talk about some
of the problems designers encounter, how to recognize
their symptoms and how to avoid them. We will focus
on the particular case of the LTC1410, a 1.25Msps,
12-bit ADC. The same considerations become important
in higher resolution ADCs at lower speeds. Conversely,
lower resolution ADCs will need this same attention at
higher speeds.
