Typical Characteristics - ADC12DL1500 (1GSPS)

Typical values are at TA = 25°C, nominal supply voltages, default full-scale voltage (FS_RANGE_A = FS_RANGE_B = 0xA000), fIN = 347MHz, AIN = –1dBFS, fCLK = 1GHz, filtered 1VPP 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 (fS / 4 and fS / 2 spurs)
