DIGITAL TO ANALOG CONVERTER

摘要

Digital to analog converters have first and second to analog arrays. The first digital to analog array has a reference input,a reference output,a first digital input that is connectable to a digital signal,and an analog output. The second digital to analog array includes a reference input, a reference output that is coupled to the reference input of the first digital to analog array,a plurality of switches coupled to the reference input,and a plurality of resistors coupled between the switches and the reference output.
