TYPICAL PERFORMANCE CHARACTERISTICS
DYNAMIC PERFORMANCE CURVES
Figure 7, Figure 8, and Figure 9 show typical FFT plots for the
AD7466, AD7467, and AD7468, respectively, at a 100 kSPS
sample rate and a 30 kHz input tone.
Figure 10 shows the signal-to-noise and distortion ratio
performance vs. input frequency for various supply voltages
while sampling at 100 kSPS with an SCLK frequency of 3.4 MHz
for the AD7466.
Figure 11 shows the signal-to-noise ratio (SNR) performance vs.
input frequency for various supply voltages while sampling at
100 kSPS with an SCLK frequency of 3.4 MHz for the AD7466.
Figure 12 shows the total harmonic distortion (THD) vs. analog
input signal frequency for various supply voltages while
sampling at 100 kSPS with an SCLK frequency of 3.4 MHz for
the AD7466.
Figure 13 shows the THD vs. analog input frequency for
different source impedances with a supply voltage of 2.7 V, an
SCLK frequency of 3.4 MHz, and sampling at a rate of 100 kSPS
for the AD7466 (see the Analog Input section).
