TPC 1, TPC 2, and TPC 3 each show a typical FFT plot for the
AD7476A, AD7477A, and AD7478A, respectively, at a 1 MSPS
sample rate and 100 kHz input frequency.
TPC 4 shows the signal-to-(noise + distortion) ratio performance
versus the input frequency for various supply voltages while sampling
at 1 MSPS with an SCLK frequency of 20 MHz for the AD7476A.
TPC 5 and TPC 6 show INL and DNL performance for the
AD7476A.

TPC 7 shows a graph of the total harmonic distortion versus 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 Analog Input section).
TPC 8 shows a graph of the total harmonic distortion versus the
analog input signal frequency for various supply voltages while
sampling at 1 MSPS with an SCLK frequency of 20 MHz.
