7.10 AC Performance: ADC3443

at maximum sampling rate, 50% clock duty cycle, AVDD = DVDD = 1.8 V, and –1-dBFS differential input (unless otherwise

noted); 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
