ADR435:  Ultralow Noise XFET® 5.0V Voltage Reference w/Current Sink and Source Capability

Product Details


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.

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 family has the capability to source up to 30 mA of output current and sink up to 20 mA. 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 8-lead MSOP and narrow SOIC packages. All versions are specified over the extended industrial temperature range of −40°C to +125°C.
