GENERAL DESCRIPTION

The SPT1019 is a monolithic 8-bit digital-to-analog converter capable of accepting video data at a 165 or 275 MWPS rate. Complete with video controls (Sync, Blank, Reference White [Force High], Bright), the SPT1019 directly drives doublyterminated 50 or 75 ohm loads to standard composite video levels. The standard setup level is 7.5 IRE. The SPT1019 is pin-compatible with the HDAC10181 with improved performance. The SPT1019 contains data and control input registers, video control logic, reference buffer, and current switches.

The SPT1019 is available in a 24-lead PDIP package in the industrial temperature range. Contact the factory for military temperature and /883 versions.
