ELECTRICAL CHARACTERISTICS (continued)
(AVDD = DVDD = CVDD = 3V, AGND = DGND = CGND = 0, fDAC = 80Msps, differential clock, external reference, VREF = 1.2V, IFS =
20mA, differential output, output amplitude = 0dBFS, TA = TMIN to TMAX, unless otherwise noted. TA ≥ +25°C, guaranteed by produc-
tion test. TA < +25°C guaranteed by design and characterization. Typical values are at TA = +25°C.)
