The ADR441-EP1 is a XFET® voltage reference featuring
ultralow noise, high accuracy, and low temperature drift
performance. Using Analog Devices, Inc., temperature drift
curvature correction and extra implanted junction FET (XFET)
technology, voltage change vs. temperature nonlinearity in the
ADR441-EP is greatly minimized.
The XFET reference offers better noise performance than buried
Zener references, and the XFET reference operates off
low supply voltage headroom (500 mV). This combination of
features makes the ADR441-EP ideally suited for precision
signal conversion applications in high end data acquisition
systems, military communication, and avionics applications.
