CHOP DISABLED
With chop disabled, the switching time or settling time is
reduced by a factor of two. However, periodic offset calibrations
may now be required to remove offset and offset drift. When
chop is disabled, the AMP-CM bit in the mode register should
be set to 1. This limits the allowable common-mode voltage that
can be used. However, the common-mode rejection degrades if
the bit is not set.
Table 11 shows the rms noise of the AD7794/AD7795 for some
of the update rates and gain settings with chop disabled.
The numbers given are for the bipolar input range with the
internal 1.17 V reference. These numbers are typical and are
generated with a differential input voltage of 0 V.
Table 12 and Table 13 show the effective resolution while the
output peak-to-peak (p-p) resolution is listed in brackets. It is
important to note that the effective resolution is calculated
using the rms noise, while the p-p resolution is calculated based
on peak-to-peak noise. The p-p resolution represents the
resolution for which there is no code flicker. These numbers are
typical and rounded to the nearest LSB.
