ADC Noise Performance with Chop Disabled (CHOP = 1)
Rev. A | Page 31 of 108
Table 14, Table 15, Table 16, and Table 17 show the output rms
noise and output peak-to-peak resolution in bits (rounded to
the nearest 0.5 LSB) for some typical output update rates. The
numbers are typical and are generated at a differential input
voltage of 0 V and a common-mode voltage of 2.5 V. The output
update rate is selected via the SF7 to SF0 bits in the SF filter
register. Note that the peak-to-peak resolution figures represent
the resolution for which there is no code flicker within a 6-
sigma limit.
The output noise comes from two sources. The first source is
the electrical noise in the semiconductor devices (device noise)
used in the implementation of the modulator. The second
source is quantization noise, which is added when the analog
input is converted to the digital domain. The device noise is at a
low level and is independent of frequency. The quantization
noise starts at an even lower level but rises rapidly with increasing
frequency to become the dominant noise source.
The numbers in the tables are given for the bipolar input ranges.
For the unipolar ranges, the rms noise numbers are the same as
the bipolar range, but the peak-to-peak resolution is based on
half the signal range, which effectively means losing 1 bit of
resolution. Typically, the performance of the ADC with chop
disabled shows a 0.5 LSB degradation over the performance
with chop enabled.
