ELECTRICAL CHARACTERISTICS (continued)

(VDD = 3.3V, OVDD = 2.0V, GND = 0, REFIN = REFOUT (internal reference), CREFOUT = 0.1µF, CL ≈ 5pF at digital outputs, VIN = -

0.5dBFS, CLKTYP = high, DCE = high, PD = low, G/T = low, fCLK = 65MHz (50% duty cycle), CREFP = CREFN = 0.1µF, 1µF in parallel with

10µF between REFP and REFN, CCOM = 0.1µF in parallel with 2.2µF to GND, 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: Specifications guaranteed by design and characterization. Devices tested for performance during production test.

Note 3: Guaranteed by design and characterization.

Note 4: During power-down, D11–D0, DOR, and DAV are high impedance.

Note 5: Digital outputs settle to VIH or VIL.
