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 doubly-
terminated 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 perfor-
mance. The SPT1019 contains data and control input regis-
ters, 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.
