AD7911/AD7921
TYPICAL PERFORMANCE CHARACTERISTICS
Figure 10 and Figure 11 show typical FFT plots for the AD7921
and AD7911, respectively, at a 250 kSPS sample rate and
100 kHz input frequency.
Rev. 0 | Page 13 of 28
Figure 12 shows the SINAD ratio performance versus the input
frequency for various supply voltages while sampling at
250 kSPS with a SCLK frequency of 5 MHz for the AD7921.
Figure 13 shows the SNR ratio performance versus the input
frequency for various supply voltages while sampling at
250 kSPS with an SCLK frequency of 5 MHz for the AD7921.
Figure 14 and Figure 15 show INL and DNL performance for
the AD7921.
Figure 16 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 a sampling rate of
250 kSPS. See the Analog Input section.
Figure 17 shows a graph of the total harmonic distortion versus
the analog input frequency for various supply voltages while
sampling at 250 kSPS with an SCLK frequency of 5 MHz.
Figure 18 shows the shutdown current versus the voltage supply
for different operating temperatures.
