Abstract :
A project to develop a new generation of letter-sorting machines for use in government postal centers and commercial applications was undertaken. A special purpose EEPROM configurable digital-to-analog convertor (DAC) chip used in an optical recognition system is described. The chip was optimized for high-speed DAC response (>25 ns) and high current switching of the DAC array with a DAC linearity of ±1/2 LSB. The optical characterization system is described
