ELECTRICAL CHARACTERISTICS
(Cont.)
At T
= full specified temperature range unless otherwise noted. +V
= LV
= +3V, specified single-ended input (1V to 2V) and sampling rate = 30MHz, unless
otherwise specified. The input range is 2.25V to 3.25V when specified for +5V operation.

UNITS
NOTES: (1) The single-ended input range is set by REFB and REFT values. (2) Spurious Free Dynamic Range refers to the magnitude of the largest harmonic.
(3) dBFS is dB relative to full scale. (4) Two-tone intermodulation distortion is referred to as the largest fundamental tone. (5) Based on (SINAD –1.76)/6.02. (6) No
“Rollover” of bits. (7) Offset deviation from ideal negative full scale.
