Figure 19 shows the power supply rejection ratio vs. supply
ripple frequency for the AD7656-1/AD7657-1/AD7658-1. 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 V
ADC at a frequency sampled, f
where:
Pf is equal to the power at Frequency f in the ADC output.
