DAC fine-tunes reference output

Keywords:Analogue-to-digital converters? digital-to-analogue? reference voltage?

Analogue-to-digital converters (ADCs) and digital-to-analogue converters (DACs) need a stable reference voltage to accurately measure or generate analogue signals. This application note shows how to adjust any three-terminal voltage reference using a resistor, a current sink/source, and a buffer amplifier to dynamically calibrate the reference, fine-tune its output value, or generate a slightly different value.
