10 / 24 page AD7910/AD7920 Rev. C | Page 10 of 24 TYPICAL PERFORMANCE CHARACTERISTICS Figure 7 and Figure 8 show a typical FFT plot for the AD7920 and AD7910, respectively, at a 250 kSPS sampling rate and a 100 kHz input frequency. Figure 9 shows the signal-to-(noise + distortion) ratio performance vs. input frequency for various supply voltages while sampling at 250 kSPS with an SCLK frequency of 5 MHz for the AD7920. Figure 10 and Figure 11 show typical INL and DNL performance for the AD7920. Figure 12 shows a graph of the total harmonic distortion vs. analog input frequency for different source impedances when using a supply voltage of 3.6 V and sampling at a rate of 250 kSPS. See the Analog Input section. Figure 13 shows a graph of the total harmonic distortion vs. analog input signal frequency for various supply voltages while sampling at 250 kSPS with an SCLK frequency of 5 MHz.
