The ADR43x series is a family of XFET® voltage references featuring low noise, high accuracy, and low temperature drift performance.

Using Analog Devices, Inc., patented temperature drift curvature correction and XFET (eXtra implanted junction FET) technology, voltage change vs.

temperature nonlinearity in the ADR43x is minimized.

Low noise (0.1 Hz to 10.0 Hz): 3.5 µV p-p @ 2.5 V output No external capacitor required Low temperature coefficient A Grade: 10 ppm/°C maximum B Grade: 3 ppm/°C maximum 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 source and sink current: +30 mA and.
20 mA Wide temperature range:.
40°C to +125°C.
