24-bit VGA Output

Postby peabody_bass » Mon Apr 19, 2010 9:02 pm

I'm trying to transition from an 8-bit VGA output to 24-bit VGA output. The former was using 3-bit Red, 3-bit Green, and 2-bit Blue through R/2R D-A converters.

I need to do 8-bit conversion for all 3 colors. Does anyone have suggestions/solutions for the output stage? It's hard to find D-A's and OpAmps that can keep up with the pixel clock (~66MHz) and aren't SMD.

Any help is appreciated. Thanks.
