MAX1209
12-Bit, 80Msps, 3.3V IF-Sampling ADC
6 _______________________________________________________________________________________
Note 1: Specifications ≥+25°C guaranteed by production test, <+25°C guaranteed by design and characterization.
Note 2: See definitions in the Parameter Definitions section.
Note 3: During power-down, D11–D0, DOR, and DAV are high impedance.
Note 4: Guaranteed by design and characterization.
Note 5: Digital outputs settle to V
IH or V IL .
Note 6: Due to test equipment jitter limitations at 175MHz, 0.15% of the spectrum on each side of the fundamental is excluded from
the spectral analysis.
