FMS3818  
Triple Video D/A Converter  
3 x 8 bit, 180 Ms/s  
Features  
Description  
• ±2.5% gain matching  
The FMS3818 is a low-cost triple D/A converter, tailored to  
fit graphics and video applications where speed is critical.  
• ±0.5 LSB linearity error  
• Internal bandgap voltage reference  
• Low glitch energy  
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  
• Single 3.3 Volt power supply  
input timing is added to the I  
override RGB inputs, setting I , I and I

zero when BLANK = L. Although appropriate for many  
applications the internal 1.25V reference voltage can be

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.
