Maxim Integrated 

14-Bit, 95Msps, 3.3V ADC

ELECTRICAL CHARACTERISTICS (continued)

(VDD = 3.3V, OVDD = 1.8V, GND = 0, REFIN = REFOUT (internal reference), VIN = -0.5dBFS, CLKTYP = high, DCE = high, PD = low,

G/T = low, fCLK = 95MHz (50% duty cycle, 1.4VP-P square wave), TA = -40°C to +85°C, unless otherwise noted. Typical values are at

TA = +25°C.) (Note 1)

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: Limit specifications include performance degradations due to a production test socket. Performance is improved when the

MAX12555 is soldered directly to the PC board.

Note 4: 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 5: During power-down, D13–D0, DOR, and DAV are high impedance.

Note 6: Digital outputs settle to VIH or VIL.

Note 7: Guaranteed by design and characterization.
