Product Introduction

Overview

The ADR550BRTZ-REEL7 is a high-precision shunt mode voltage reference produced by Analog Devices Inc. This component is designed for space-critical applications and is housed in an ultrasmall 3-Lead SOT-23-3 package. It is part of the ADR520/ADR525/ADR530/ADR540/ADR550 series, which are known for their low temperature drift, high initial accuracy, and ultralow output noise. The ADR550BRTZ-REEL7 is particularly suited for handheld, battery-powered applications due to its low operating current and ease of use.
