GENERAL DESCRIPTION

The SPT1018 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 SPT1018 directly drives doubly-terminated 50 or 75 ohm loads to standard composite video levels. The standard set-up level is 7.5 IRE. The SPT1018 is pin-compatible with the HDAC10180 and the TDC1018, with improved performance. The SPT1018 contains data and control input registers, video control logic, reference buffer, and current switches.
