ADR291/ADR292 TERMINOLOGY Line Regulation Line regulation refers to the change in output voltage due to a specified change in input voltage. It includes the effects of self- heating. Line regulation is expressed as percent-per-volt, parts- per-million-per-volt, or microvolts-per-volt change in ...

THEORY OF OPERATION The ADR291/ADR292 series of references uses a reference generation technique known as XFET (eXtra implanted junc- tion FET). This technique yields a reference with low noise, low supply current, and very low thermal hysteresis. The core of ...
