ADC09xJ800-Q1 is a family of quad, dual and single channel, 9-bit, 800 MSPS analog-to-digital converters (ADC). Low power consumption, high sampling rate and 9-bit resolution makes the ADC09xJ800-Q1 suited for light detection and ranging (LiDAR) systems. The ADC09xJ800-Q1 is qualified for automotive applications.
Full-power input bandwidth (-3 dB) of 6 GHz provides flat frequency response for frequency modulated continuous wave (FMCW) LiDAR systems and provides a narrow impulse response for pulse-based systems. The full-power input bandwidth also enables direct RF sampling of up to 4 GHz.
