NOTES: (1) Spurious-Free Dynamic Range refers to the magnitude of the largest harmonic.
(2) dBFS means dB relative to Full-Scale.
(3) 2-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 on the
OE
pin.
(6) Includes internal reference.
