Overview
The ADR01AR-REEL7, produced by Analog Devices Inc., is a precision 10.0 V voltage reference device. It is part of the ADR01 series, which includes compact, low drift voltage references designed to provide stable output voltages over a wide supply voltage range. These devices are available in ultracompact SC70 and TSOT packages, as well as in an 8-lead SOIC package, making them ideal for general-purpose and space-constrained applications.
The ADR01 series is known for its high accuracy, high stability, and low power consumption. The SOIC versions of the ADR01 are drop-in replacements for industry-standard REF01 devices, offering compatibility and ease of integration into existing designs.
