MAX1418

15-Bit, 65Msps ADC with -78.2dBFS

Noise Floor for IF Applications

4 _______________________________________________________________________________________

Note 1: Dynamic performance is based on a 32,768-point data record with a sampling frequency of f

SAMPLE

= 65.0117120MHz, an

input frequency of f

= f

SAMPLE

x (35283/32768) = 70.001472MHz, and a frequency bin size of 1984Hz. Close-in (f

±23.8kHz) and low-frequency (DC to 47.6kHz) bins are excluded from the spectrum analysis.

Note 2: Apply the same voltage levels to DV

and DRV

Note 3: Guaranteed by design and characterization.
