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.

FEATURES
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
Wide operating range
   ADR430: 4.1 V to 18 V
   ADR431: 4.5 V to 18 V
   ADR433: 5.0 V to 18 V
   ADR434: 6.1 V to 18 V
   ADR435: 7.0 V to 18 V
   ADR439: 6.5 V to 18 V
High output current: +30 mA/−20 mA
Wide temperature range: −40°C to +125°C

APPLICATIONS
Precision data acquisition systems
High resolution data converters
Medical instruments
Industrial process control systems
Optical control circuits
Precision instruments
