TYPICAL PERFORMANCE CHARACTERISTICS
Figure 7, Figure 8, and Figure 9 each show a typical FFT plot for
the AD7476A, AD7477A, and AD7478A, respectively, at a
1 MSPS sample rate and 100 kHz input frequency. Figure 10
shows the signal-to-(noise + distortion) ratio performance vs.
the input frequency for various supply voltages while sampling
at 1 MSPS with an SCLK frequency of 20 MHz for the
AD7476A.
Figure 11 and Figure 12 show INL and DNL performance for
the AD7476A. Figure 13 shows a graph of the total harmonic
distortion vs. the analog input frequency for different source
impedances when using a supply voltage of 3.6 V and sampling
at a rate of 1 MSPS (see the Analog Input section). Figure 14
shows a graph of the total harmonic distortion vs. the analog
input signal frequency for various supply voltages while
sampling at 1 MSPS with an SCLK frequency of 20 MHz.
