Channel-to-Channel Isolation
Channel-to-channel isolation is a measure of the level of crosstalk
between any two channels. It is measured by applying a full-scale,
100 kHz sine wave signal to all unselected input channels and
determining the degree to which the signal attenuates in the
selected channel with a 50 kHz signal. Figure 14 shows the
worst case across all eight channels for the AD7329. The analog
input range is programmed to be ±2.5 V on the selected channel
and ±10 V on all other channels.
Intermodulation Distortion
With inputs consisting of sine waves at two frequencies, fa and
fb, any active device with nonlinearities creates distortion
products at sum and difference frequencies of mfa ± nfb, where
m, n = 0, 1, 2, 3, and so on. Intermodulation distortion terms
are those for which neither m nor n are equal to 0. For example,
the second-order terms include (fa + fb) and (fa fb), whereas
the third-order terms include (2fa + fb), (2fa fb), (fa + 2fb),
and (fa 2fb).
The AD7329 is tested using the CCIF standard where two input
frequencies near the top end of the input bandwidth are used.
In this case, the second-order terms are usually distanced in
frequency from the original sine waves, whereas the third-order
terms are usually at a frequency close to the input frequencies.
As a result, the second- and third-order terms are specified
separately. The calculation of the intermodulation distortion is
per the THD specification, where it is the ratio of the rms sum
of the individual distortion products to the rms amplitude of
the sum of the fundamentals expressed in decibels.
Power Supply Rejection (PSR)
Variations in power supply affect the full-scale transition but
not the linearity of the converter. Power supply rejection is the
maximum change in the full-scale transition point due to a
change in power supply voltage from the nominal value (see the
Common-Mode Rejection Ratio (CMRR)
CMRR is defined as the ratio of the power in the ADC output at
full-scale frequency, f, to the power of a 100 mV sine wave
applied to the common-mode voltage of the VIN+ and VIN
frequency, fS, as
CMRR (dB) = 10 log (Pf/PfS)
where Pf is the power at frequency f in the ADC output, and PfS
is the power at frequency fS in the ADC output (see Figure 17).
