Overview
The ADR392AUJZ-REEL7 is a precision voltage reference from Analog Devices Inc., part of the ADR39x family. This component is designed to provide a stable output voltage of 4.096 V with high precision and low power consumption. It features a compact 5-lead TSOT package and utilizes patented temperature drift curvature correction techniques to achieve a low temperature coefficient of 9 ppm/°C for the B grade and 25 ppm/°C for the A grade. This makes it ideal for battery-operated applications due to its low power operation, small size, and ease of use.
