The ADR43x series is a family of XFET voltage references
featuring low noise, high accuracy, and low temperature drift
performance. Using ADI’s patented temperature drift curvature
correction and XFET (eXtra implanted junction FET) technology,
the ADR43x’s voltage change versus temperature nonlinearity is
minimized.
The XFET references operate at lower current (800 μA) and
supply headroom (2 V) than buried-Zener references. Buried-
Zener references require more than 5 V headroom for operations.
The ADR43x XFET references are the only low noise solutions
for 5 V systems.
The ADR43x series has the capability to source up to 30 mA
and sink up to 20 mA of output current. It also comes with a
TRIM terminal to adjust the output voltage over a 0.5% range
without compromising performance. The ADR43x is available
in the 8-lead mini SOIC and 8-lead SOIC packages.
All versions are specified over the extended industrial tempera-
ture range (40°C to +125°C).
