NOTES: (1) Spurious-Free Dynamic Range refers to the difference in magnitude between the fundamental and the next largest harmonic. (2) dBFS means dB
relative to full scale. (3) Effective number of bits (ENOB) is defined by (SINAD – 1.76)/6.02. (4) Internal 50kΩ pull-down resistor. (5) Includes internal reference.
(6) Excludes internal reference. (7) Typical reference tolerance based on ±1 sigma of distribution.
