7.7 Electrical Characteristics: General
Typical values are over the operating free-air temperature range, at T_A = 25°C, full temperature range is T_MIN = –40°C to T_MAX
= 85°C, maximum sampling rate, 50% clock duty cycle, AVDD = DVDD = 1.8 V, and –1-dBFS differential input, unless
otherwise noted.
