typical values are at T_A = 25°C, full temperature range is from T_MIN = –40°C to T_MAX = +100°C, device sampling frequency = 1 GSPS, 50% clock duty cycle, AVDD19 = 1.9 V, AVDD = DVDD = 1.15 V, –1-dBFS differential input, and f_IN = 190 MHz (unless otherwise noted)

f_IN = 230 MHz, A_IN= –1 dBFS, SNR = 68.11 dBFS,
SFDR = 77.01 dBc, interleaving spur = –42.85 dBFS
