ADR550BKSZ-REEL7

Overview

The ADR550BKSZ-REEL7 is a high precision shunt voltage reference manufactured by Analog Devices Inc. It provides a nominal output voltage of 5.0 V with an initial accuracy of ±0.2% and a maximum temperature coefficient of 40 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 is housed in an ultracompact SC-70 package.

Feature Summary

• Ultracompact SC-70 package design for space-critical applications
• Low temperature drift of 40 ppm/°C (maximum)
• Initial accuracy better than ±0.2%
• Trim terminal allows adjustment of the output voltage over a ±0.5% range

Applications

• Portable, battery-powered equipment
• Automotive systems
• Power supplies
• Data acquisition systems
• Instrumentation and process control

Procurement Notes

Verify the specific ordering suffix 'BKSZ' against official documentation to confirm RoHS compliance status and exact packaging configuration. Ensure the SC-70 package dimensions align with PCB layout requirements. Confirm that the 5.0 V output voltage matches the system design specifications before procurement.

Selection Notes

Select this component when a precise 5.0 V reference is required in a minimal footprint. The B-grade accuracy ensures tight tolerance without external calibration. Verify that the available bias current falls within the 50 μA to 15 mA operational window for the intended application environment.

Part Context

This part belongs to the ADR520/ADR525/ADR530/ADR540/ADR550 series of high precision shunt mode voltage references. These devices utilize band gap technology to achieve stable performance across varying temperatures. The series offers multiple voltage options packaged in SC-70 or SOT-23-3 formats.

Replacement Considerations

The datasheet indicates pin compatibility with the LM4040/LM4050 series.
