GENERAL DESCRIPTION

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

lower supply voltage headroom (2 V) than buried Zener

references. Buried Zener references require more than 5 V

headroom for operation. 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 8-lead narrow

SOIC packages. All versions are specified over the extended

industrial temperature range of −40°C to +125°C.
