GENERAL DESCRIPTION
The ADR431-EP/ADR434-EP/ADR435-EP are XFET® voltage
references featuring low noise, high accuracy, and low temperature
drift performance. Using Analog Devices, Inc., patented temperature
drift curvature correction and eXtra implanted junction FET
(XFET) technology, voltage change vs. temperature nonlinearity
in the ADR431-EP/ADR434-EP/ADR435-EP is minimized.
The ADR431-EP/ADR434-EP/ADR435-EP have the capability to
source up to +10 mA of output current and sink up to −10 mA.
They also come with a trim terminal to adjust the output voltage
over a 0.5% range without compromising performance.
The ADR431-EP/ADR434-EP/ADR435-EP are available in an
8-lead narrow SOIC package and are specified over the military
temperature range of −55°C to +125°C.
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 ADR431-EP/ADR434-EP/
ADR435-EP XFET references are optimal low noise solutions for
5 V systems.
Additional application and technical information can be found in
the ADR430/ADR431/ADR433/ADR434/ADR435 data sheet.
