6.11 AC Performance: ADC3224

At maximum sampling rate, 50% clock duty cycle, AVDD = DVDD = 1.8 V, and –1-dBFS differential input. Typical values are specified at an ambient temperature of 25°C. Minimum and maximum values are specified over an ambient temperature range of –40°C to +85°C (unless otherwise noted).
