PRELIMINARY TECHNICAL DATA

AD7273/AD7274

PERFORMANCE CURVES

Dynamic Performance curves

TPC 1 and TPC 2 show typical FFT plots for the AD7274

and AD7273 respectively, at 3 MSPS sample rate and TBD

KHz input tone.

TPC 3 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 AD7274.

TPC 4 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 AD7274.

TPC 5 shows a graph of the Total Harmonic Distortion

(THD) versus Analog input signal frequency for various

supply voltages while sampling at 3 MSPS with a SCLK

frequency of 52 MHz for the AD7274.

TPC 6 shows a graph of the Total Harmonic Distortion

(THD) 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 AD7274. See Analog Input section.

TPC 7 shows the Power Supply Rejection Ratio (PSRR)

versus Supply Ripple Frequency for the AD7274 when no

decoupling is used. See PSRR in the Terminology section.
