• Manufacturer Part Number: ADS824
• Description: 10-Bit/ 70MHz Sampling ANALOG-TO-DIGITAL CONVERTER
• Manufacturer: Burr-Brown Corporation

SPECIFICATIONS
At T
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
reference. (7) Excludes internal reference.
