Description
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, setting IOG, IOB and IOR currents to zero when BLANK = L. Although appropriate for many applications the internal 1.25V reference voltage can be overridden by the VREF input. Few external ponents are required, just the current reference resistor, current output load resistors, bypass capacitors and decoupling capacitors. Package is a 48-lead LQFP. Fabrication technology is CMOS. Performance is guaranteed from 0 to 70°C.
