APPLICATIONS Precision data acquisition systems High resolution data converters Battery-powered instrumentation Precision instruments Military communication Unmanned systems Avionics GENERAL DESCRIPTION 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. 1 The ADR441-EP has the capability to source up to +10 mA of output current and sink up to −5 mA. The device also comes with a trim terminal to adjust the output voltage over a 0.5% range without compromising performance. The ADR441-EP is available in an 8-lead, narrow SOIC package. The ADR441-EP is specified over the military temperature range of −55°C to +125°C. Additional application and technical information can be found in the ADR441 data sheet.
