NOTES: (1) Spurious Free Dynamic Range refers to the magnitude of the largest harmonic. (2) dBFS means dB relative to Full Scale. (3) Two-tone
intermodulation distortion is referred to the largest fundamental tone. This number will be 6dB higher if it is referred to the magnitude of the two-tone fundamental
envelope. (4) Effective number of bits (ENOB) is defined by (SINAD – 1.76)/6.02. (5) A 50k
pull-down resistor is inserted internally. (6) Includes internal
reference. (7) Excludes internal reference.
SPECIFICATIONS
(CONT)
At T
= full specified temperature range, single-ended input range = 1.5V to 3.5V, sampling rate = 75MHz, convert command clock = +3V, external reference unless
otherwise noted.
