Figure 19 shows the power supply rejection ratio vs. supply
ripple frequency for the AD7656/AD7657/AD7658.
The power supply rejection ratio is defined as the ratio
of the power in the ADC output at full-scale frequency, f,
to the power of a 200 mV p-p sine wave applied to the
ADC’s VDD and VSS supplies of frequency fS
PSRR (dB) = 10 log (Pf/PfS)
where:
Pf is equal to the power at frequency f in the ADC output.
PfS is equal to the power at frequency fS coupled onto the VDD
and VSS supplies.
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 30 kHz signal.
% FSR
%FSR is calculated using the full theoretical span of the ADC.
