1 CHANNEL 8-BIT VIDEO A/D CONVERTER
MB40558
s DESCRIPTION
The Fujitsu MB40558 is a low power ultra-high speed video A/D converter fabricated with Fujitsu Advanced Bipolar Technology. The MB40558 also adopts the fully-parallel comparision technique (flash method) for high speed conversion and can concert wide bandanalog signal such as video signal to digital signal at sampling rate of DC through 40 Mega-samples/sec. Because of such high speed operation, the MB40558 is suitable for digital video applications such as the digital TV, video processing with computer, or ladder signal processing.
