Description

   FMS3810/3815 products are low-cost triple D/A converters  that are tailored to fit graphics and video applications where  speed is critical. Two speed grades are available:

   TTL-level inputs of FMS3810/3815 are converted to analog current outputs that can drive 2537.5Ω loads corresponding to doubly-terminated 5075Ω 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 1.235V reference voltage can be overridden by the VREF input.

   Few external components of FMS3810/3815 are required, just the current reference resistor, current output load resistors, and decoupling capacitors.

   Package of FMS3810/3815 is a 48-lead LQFP. Fabrication technology is CMOS. Performance is guaranteed from 0 to 70°C.
