ELECTRICAL CHARACTERISTICS (continued)
(AV DD = DV DD = CV DD = 3V, AGND = DGND = CGND = 0, f DAC = 165Msps, no interpolation, external reference, V REF = 1.2V,
I FS = 20mA, output amplitude = 0dB FS, differential output, T A = T MIN to T MAX , unless otherwise noted. T A > +25°C guaranteed by
production test. T A < +25°C guaranteed by design and characterization. Typical values are at T A = +25°C.)
