PRELIMINARY TECHNICAL DATA

PERFORMANCE CURVES

TPC 1 shows a typical FFT plot for the AD7680 at

100kSPS sample rate and 10kHz input frequency. TPC 2

shows the signal-to-(noise+distortion) ratio performance

versus input frequency for various supply voltages while

sampling at 100kSPS with an SCLK of 2.5MHz.

TPC 3 shows a graph of total harmonic distortion versus

analog input frequency for various supply voltages, while

TPC 4 shows a graph of total harmonic distortion versus

analog input frequency for various source impedances. See

Analog Input section.

TPC 5 and TPC 6 show typical DNL and INL plots for

the AD7680.
