MB40578

FUJITSU SEMICONDUCTOR DATA SHEET DS04-28202-6E ASSP 1 CHANNEL 8-BIT VIDEO A/D CONVERTER MB40578 s DESCRIPTION The Fujitsu MB40578 is a low power ultra-high speed video A/D converter fabricated with Fujitsu Advanced Bipolar Technology. The MB40578 also adopts the fully-parallel comparison technique (flash method) for high speed convertion and can convert wide band analog signal such as video signal to digital signal at a sampling rate of DC through 20 Mega-samples/sec. Because of such high-speed poeration, the MB40578 is suitable for digital video applications such as the digital TV, video processing with computer, or radar signal processing. s FEATURES Resolution: Linearity error: Maximum conversion rate: Analog input voltage: Digital I/O level: Single power supply: Power Dissipation: Package: 8 bits ±0.2% max.
