5.16 Typical Characteristics - ADC12DL2500 (2.5GSPS)

Typical values are at T_A = 25°C, nominal supply voltages, default full-scale voltage (FS_RANGE_A = FS_RANGE_B = 0xA000), f_IN = 347MHz, A_IN = –1dBFS, f_CLK = 2.5GHz, filtered 1V_PP sine-wave clock, DES_EN = 1, LDEMUX = 1, LALIGNED = 0, ADC_DITH = 0x01, LVDS driver high-swing mode (HSM) and foreground calibration; SNR results exclude DC, HD2 to HD9 and interleaving spurs; SINAD, ENOB, and SFDR results exclude DC and signal-independent interleaving spurs (f_S / 4 and f_S / 2 spurs)
