ELECTRICAL CHARACTERISTICS DYNAMIC PERFORMANCE (continued)

Typical values are at 25°C, AVDD = 1.8 V, LVDD = 1.8 V, 50% clock duty cycle, –1 dBFS differential analog input, Sample

rate = 80 MSPS, ADC is configured in internal reference mode (unless otherwise noted). MIN and MAX values are across the

full temperature range TMIN = –40°C to TMAX = 85°C, AVDD = 1.8 V, LVDD = 1.8 V.
