ADR550ARTZ-REEL7

Overview

The ADR550ARTZ-REEL7 is a high precision shunt voltage reference from Analog Devices, housed in an ultracompact 3-Lead SOT-23-3 package. It provides a fixed output voltage of 5.0 V with an initial accuracy of ±0.4% and a maximum temperature coefficient of 70 ppm/°C. The device operates within an industrial temperature range of −40°C to +85°C and requires an operating current between 50 μA and 15 mA. It features low output voltage noise of 38 μV p-p (0.1 Hz to 10 Hz) and includes a trim terminal for adjusting the output voltage over a ±0.5% range without affecting the temperature coefficient.

Procurement Notes

Verify the specific grade and packaging configuration against the official Analog Devices ordering guide before procurement. Confirm that the selected component matches the required initial accuracy and temperature coefficient specifications for the intended application environment. Ensure compliance with RoHS directives if applicable to the project requirements.

Selection Notes

Select this component when a precise 5.0 V reference is needed in a small footprint. Consider the ±0.4% initial accuracy and 70 ppm/°C temperature coefficient limits. Verify that the bias resistor selection keeps the operating current within the 50 μA to 15 mA range across all supply and load conditions.

Part Context

This part belongs to the ADR520/ADR525/ADR530/ADR540/ADR550 series of high precision shunt mode voltage references.
