Overview
The REF195GRUZ is a precision micropower low dropout voltage (LDV) reference produced by Analog Devices Inc. This device is part of the REF195 series and is designed to provide a stable output voltage with high accuracy and low temperature drift. It utilizes a patented temperature drift curvature correction circuit and laser trimming of highly stable, thin-film resistors to achieve its performance characteristics.
The REF195GRUZ is particularly suited for applications requiring a reliable and precise voltage reference, such as portable instruments, analog-to-digital converters (ADCs), digital-to-analog converters (DACs), smart sensors, and solar-powered applications.
