AD7732
OUTPUT NOISE AND RESOLUTION SPECIFICATION
The AD7732 can be operated with chopping enabled or
disabled, allowing the ADC to be programmed to either
optimize the throughput rate and channel switching time or to
optimize the offset drift performance. Noise tables for these two
primary modes of operation are outlined below for a selection
of output rates and settling times.
Rev. 0 | Page 10 of 32
The AD7732 noise performance depends on the selected
chopping mode, the filter word (FW) value, and the selected
analog input range. The AD7732 noise will not vary
significantly with MCLK frequency.
Chopping Enabled
The first mode, in which the AD7732 is configured with
chopping enabled (CHOP = 1), provides very low noise with
lower output rates. Table 4 to Table 6 show the –3 dB
frequencies and typical performance versus the channel
conversion time and equivalent output data rate, respectively.
shows the typical output rms noise. Table 5 shows the typical
effective resolution based on rms noise. Table 6 shows the
typical output peak-to-peak resolution, representing values for
which there will be no code flicker within a 6-sigma limit. The
peak-to-peak resolutions are not calculated based on rms noise
but on peak-to-peak noise.
These typical numbers are generated from 4096 data samples
acquired in continuous conversion mode with an analog input
voltage set to 0 V and MCLK = 6.144 MHz. The conversion
time is selected via the channel conversion time register.
