6.5 Electrical Characteristics - Power Consumption

Typical values are over the operating free-air temperature range, at TA = 25°C, full temperature range is TMIN = –

40°C to TMAX = 105°C, ADC sampling rate = 65 MSPS, 50% clock duty cycle, AVDD, IOVDD = 1.8 V, and –1-

dBFS differential input, unless otherwise noted
