Preliminary Technical Data

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.

DC Accuracy curves

TPC 8and TPC 9 show typical INL and DNL performance

for the AD7276.

TP10 and TPC11 show Change in DNL and INL versus

Reference Voltage when using a supply voltage of 3V.

Power Requirements curves

TPC12 shows Maximum current versus Supply voltage for

the AD7274 with different SCLK frequencies.
