AN629 Digitally Adjustable Voltage References

DIGITAL POTENTIOMETERS Jul 01, 2001 Digitally Adjustable Voltage References A digitally adjustable voltage reference is useful in many applications. For instance, it can be used to finely tune the reference voltage when absolute accuracy is required or to adjust the reference voltage to match the full-scale voltage range of an analog-input signal to maximize the dynamic range of an analog-to-digital conversion. You can easily create one by combining an adjustable voltage reference with a digit.
