ADR540BRT-R2

Overview

The ADR540BRT-R2 is a high precision shunt mode voltage reference manufactured by Analog Devices Inc. It provides a nominal output voltage of 4.096 V with an initial accuracy of ±0.2% and a maximum temperature coefficient of 40 ppm/°C. The device operates within a current range of 50 μA to 15 mA and functions in the industrial temperature range of −40°C to +85°C. It is housed in a 3-Lead SOT-23-3 package.

Feature Summary

Ultracompact packaging in SC70 and SOT-23-3 form factors for space-critical applications
Low temperature drift of 40 ppm/°C with initial accuracy better than ±0.2%
Operates without requiring an external compensation capacitor while remaining stable with any capacitive load
Includes a trim terminal allowing adjustment of the output voltage over a ±0.5% range

Applications

Portable, battery-powered equipment
Automotive systems
Data acquisition systems
Instrumentation and process control
Energy measurement

Procurement Notes

Verify the specific ordering suffix R2 against official documentation to confirm reel quantity and branding details. Ensure the component matches the 3-Lead SOT-23-3 package type required for the design. Confirm RoHS compliance status if environmental regulations apply to the target assembly. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and revision level before procurement.

Selection Notes

Select this component when a precise 4.096 V reference is needed in a small footprint. The low minimum operating current of 50 μA makes it suitable for battery-powered designs. Verify that the bias resistor calculation accommodates the full operating current range from 50 μA to 15 mA under varying supply and load conditions. Consider the trim terminal if system-level error correction is required without affecting temperature stability.

Part Context

This part belongs to the ADR520/ADR525/ADR530/ADR540/ADR550 series of high precision shunt voltage references. These devices utilize band gap concepts to produce stable references suitable for high accuracy data acquisition components. The series offers various output voltages including 2.048 V, 2.5 V, 3.0 V, 4.096 V, and 5.0 V across different grades.
