ELECTRICAL CHARACTERISTICS
Typical values are at 25°C, min and max values are across the full temperature range T_MIN = –40°C to T_MAX = 85°C, AVDD =
DRVDD = 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.
