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 at the end of this data sheet.
Note 3: Specifications guaranteed by design and characterization. Devices tested for performance during production test.
Note 4: During power-down, D13–D0, DOR, and DAV are high impedance.
Note 5: Guaranteed by design and characterization.
Note 6: Digital outputs settle to V_IH or V_IL.
Note 7: 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.
Note 8: Limit specifications include performance degradations due to a production test socket. Performance is improved when the
MAX12553 is soldered directly to the PC board.
