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 25–37.5loads corresponding to doubly-
terminated 50–75loads. 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 components 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.
