ABSTRACT
The article focuses on the use of digitally controlled potentiometer (DCP) in adjusting the output of voltage reference device. DCP can be used in adjusting the output voltage without changing the temperature coefficient (TC) of the device and even without a trim pin for fine-tuning. DCP with a dominating resistance can also externally biased the voltage reference with trim pin to achieve an adjustable output. Several graphs and model that illustrate the flow of the DCP in the voltage reference are presented.
