ADS826E(1) Burr-Brown Corporation, ADS826E(1) Datasheet - Page 3

• Manufacturer Part Number: ADS826E(1)
• Description: 10-Bit/ 60MHz Sampling ANALOG-TO-DIGITAL CONVERTER
• Manufacturer: Burr-Brown Corporation

ELECTRICAL CHARACTERISTICS
At T
NOTES: (1) ADS826 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) 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 2-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. (9) Ensured by design.
