PERFORMANCE CURVES
Dynamic Performance curves
TPC 1, TPC 2 and TPC 3 show typical FFT plots for the
AD7276, AD7277 and AD7278 respectively, at 3 MSPS
sample rate and TBD KHz input tone.
TPC 4 shows the Signal-to-(Noise+Distortion) Ratio
performance versus Input frequency for various supply
voltages while sampling at 3 MSPS with a SCLK frequency
of 52 MHz for the AD7276.
TPC 5 shows the Signal to Noise Ratio (SNR) performance
versus Input frequency for various supply voltages while
sampling at 3 MSPS with a SCLK frequency of 52 MHz for
the AD7276.
TPC 6 shows a graph of the Total Harmonic Distortion
versus Analog input signal frequency for various supply
voltages while sampling at 3 MSPS with a SCLK frequency
of 52 MHz for the AD7276.
TPC 7 shows a graph of the Total Harmonic Distortion
versus Analog input frequency for different source impedances
when using a supply voltage of TBD V,
SCLK frequency of
52 MHz
and sampling at a rate of 3 MSPS for the AD7276.
See Analog Input section.
