TYPICAL PERFORMANCE CHARACTERISTICS
and AD7912, respectively, at a 1 MSPS sample rate and 100 kHz
input frequency.
Figure 12 shows the SINAD performance versus the input
frequency for various supply voltages while sampling at 1 MSPS
with a SCLK frequency of 18 MHz for the AD7922.
Figure 13 shows the SNR performance versus the input fre-
quency for various supply voltages while sampling at 1 MSPS
with an SCLK frequency of 18 MHz for the AD7922.
Figure 14 and Figure 15 show INL and DNL performance for
the AD7922.
Figure 16 shows a graph of the THD versus the analog input
frequency for different source impedances when using a supply
voltage of 3.6 V and a sampling rate of 1 MSPS. See the Analog
Input section.
Figure 17 shows a graph of the THD versus the analog input
frequency for various supply voltages while sampling at 1 MSPS
with an SCLK frequency of 18 MHz.
Figure 18 shows the shutdown current versus the voltage supply
for different operating temperatures.
