3 Description
ADC12xJ800-Q1 is a family of quad, dual and
single channel, 12-bit, 800 MSPS analog-to-digital
converters (ADC). Low power consumption, high
sampling rate and 12-bit resolution makes the
ADC12xJ800-Q1 suited for light detection and ranging
(LiDAR) systems. The ADC12xJ800-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 of L-band and S-band.
