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 are converted to analog current outputs that can drive 25-37.5W loads corresponding to doubly-terminated 50-75W 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 are required, just the current reference resistor, current output load resistors, and decoupling capacitors.
Package is a 48-lead LQFP. Fabrication technology is CMOS. Performance is guaranteed from 0 to 70°C.
