AC Performance: ADC3244 (continued)
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, ADC sampling rate = 125 MSPS, 50% clock duty cycle, AVDD = DVDD = 1.8 V, and –1-dBFS differential input,
unless otherwise noted.
