MAX5140 Datasheet, PDF (1/12 Pages) Maxim Integrated Products – 8-Bit, Ultra-High-Speed DAC

19-1205; Rev 2; 5/98
8-Bit, Ultra-High-Speed DAC
________________General Description
The MAX5140 is a monolithic, 8-bit digital-to-analog
converter (DAC) capable of accepting video data at
400Msps. Complete with video controls (sync, blank,
reference white (force high), and bright), the MAX5140
directly drives doubly terminated 50Ω or 75Ω loads to
standard composite video levels. Standard setup level
is 7.5IRE. The MAX5140 includes an internal precision
bandgap reference that can drive two other MAX5140s
in an RGB graphics system.
The MAX5140 is available in a 24-pin PDIP package in
the -20°C to +85°C industrial temperature range.
