FMS3818 - Fairchild Semiconductor

FMS3818 Triple Video D/A Converter

The FMS3818 is a low-cost triple D/A converter, tailored to fit graphics and video applications where speed is critical. CMOS-level inputs are converted to analog current outputs that can drive 25–37.5Ω loads corresponding to doublyterminated 50–75Ω loads. A sync current following SYNC input timing is added to the IOG output. BLANK will override RGB inputs, s.
