Indicates the same specifications as the ADS822E.
NOTES: (1) ADS825E accepts a +3V clock input. (2) Spurious Free Dynamic Range refers to the magnitude of the largest harmonic. (3) dBFS means dB relative to Full Scale. (4) 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. (5) Effective number of bits (ENOB) is defined
by (SINAD – 1.76)/6.02. (6) A 50k
pull-down resistor is inserted internally on OE pin. (7) Includes internal reference. (8) Excludes internal reference.
