5.8 Timing Requirements

Typical values are at TA = 25°C, MIN and MAX timing values are characterized over the full temperature range TMIN = –55°C

to TMAX = 105°C and are NOT production tested, ADC sampling rate = 65 MSPS, 50% clock duty cycle, AVDD = IOVDD =

1.8 V, 1.6 V external reference, and –1-dBFS differential input, unless otherwise noted
