ELECTRICAL CHARACTERISTICS (continued)
Typical values are at 25
°C, AVDD = 3.3V, DRVDD = 1.8 V to 3.3 V, maximum rated sampling frequency, 50% clock duty
cycle,
–1 dBFS differential analog input, internal reference mode, applies to CMOS and LVDS interfaces, unless otherwise
noted.
Min and max values are across the full temperature range TMIN = –40°C to TMAX = 85°C, AVDD = 3.3 V, DRVDD = 3.3 V,
unless otherwise noted.
