GENERAL DESCRIPTION

The SPT5230 is a 10-bit, 36 MWPS triple video digital-to-

analog converter specifically designed for high performance,

high resolution color graphics monitor applications and video

processing applications. A single external resistor controls

the full-scale output current. The differential linearity errors of

the DACs are guaranteed to be a maximum of ±1.0 LSB over

the full temperature range. The device is available in a 52-

lead QFP package over the commercial temperature range.
