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.

Low noise (0.1 Hz to 10 Hz): 3.5 μV p-p @ 2.5 V output

No external capacitor required

Low temperature coefficient

A Grade: 10 ppm/°C max

B Grade: 3 ppm/°C max

Load regulation: 15 ppm/mA

Line regulation: 20 ppm/V
