TYPICAL PERFORMANCE CHARACTERISTICS
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.
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.
