Fujitsu MB40568
The MB40568 is an all-parallel (flash type) A/D converter for 8-bit video applications, and uses high-speed bipolar process technology for low-power consumption and high-speed conversion. This A/D converter is capable of converting analog signals into digital signals at a rate of DC to 20 MSPS (megasamples per second). Additional circuitry including a clamp circuit and reference voltage generator circuits are build in, to make the MB40568 ideally suited for video signal processing.DESCRIPTION
