Typical Characteristics: ADC3424 (continued)

Typical values are at TA = 25°C, ADC sampling rate = 125 MSPS, 50% clock duty cycle, AVDD = 1.8 V, DVDD = 1.8 V, –1-

dBFS differential input, 2-VPP full-scale, 32k-point FFT, chopper disabled, and SNR reported with a 1-MHz offset from dc

when chopper is disabled and from fS / 2 when chopper is enabled, unless otherwise noted.
