Power Supply Rejection Ratio (PSRR)
The power supply rejection ratio is the ratio of the power in
the ADC output at full-scale frequency, f, to the power of a
100 mV p-p sine wave applied to the ADC VDD supply of
frequency fS. The frequency of this input varies from 1 kHz to
1 MHz.
AD7440/AD7450A
PSRR (dB) = 10log(Pf/PfS)
Pf is the power at frequency f in the ADC output; Pfs is the
power at frequency fS in the ADC output.
