ELECTRICAL CHARACTERISTICS (continued)

(VDD = 3.3V, OVDD = 2.0V, GND = 0, REFIN = REFOUT (internal reference), VIN = -0.5dBFS, CLKTYP = high, DCE = high, PD = low,

G/T = low, fCLK = 80MHz (50% duty cycle), 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.

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 VIH or VIL.
