A high speed EEPROM configurable digital to analog convertor array

Abstract

A special purpose EEPROM configurable Digital to Analog convertor 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. A description of the optical characterization system will also be presented.6.6.1
