supplies must always remain above the mini-
mum specification.
As with any high-precision A/D converter, the
CS5126 requires careful attention to grounding
and layout arrangements. However, no unique
layout issues must be addressed to properly ap-
ply the CS5126. The CDB5126 evaluation board
is available for the CS5126, which avoids the
need to design, build, and debug a high-preci-
sion PC board to initially characterize the part.
The board comes with a socketed CS5126, and

Power Supply Rejection
The CS5126 features a fully differential compa-
rator design, resulting in superior power supply
rejection. Rejection is further enhanced by the
on-chip self-calibration and "auto-zero" process.
Figure 14 shows worst-case rejection for all
combinations of conversion rates and input con-
ditions.
