GENERAL DESCRIPTION
The SPT5100 is an 8-bit, 20 MWPS, dual channel video digital-
to-analog converter specifically designed for video process-
ing applications including digital TV decoders and digital
VCRs. A single external resistor controls the full-scale output
current. The differential linearity errors of the DACs are
guaranteed to be a maximum of ±0.5 LSB over the full
temperature range. The device is available in a 32-lead QFP
package in the commercial temperature range.
