GENERAL DESCRIPTION

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. BuriedZener 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.
