GENERAL DESCRIPTION
The ADR43x series is a family of XFET? voltage references

drift curvature correction and XFET (eXtra implanted junction
FET) technology, voltage change vs. temperature nonlinearity in
the ADR43x is minimized.
The XFET references operate at lower current (800 μA) and
lower supply voltage headroom (2 V) than buried Zener
references. Buried Zener references require more than 5 V
headroom for operation. The ADR43x XFET references are
the only low noise solutions for 5 V systems.
The ADR43x family has the capability to source up to 30 mA of
output current and sink up to 20 mA. It also comes with a trim
terminal to adjust the output voltage over a 0.5% range without
compromising performance.
