Description
FMS3810/3815 products are low-cost triple D/A converters
that are tailored to t 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 25–37.5
loads corresponding to doubly-terminated
50–75
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.
