ADR550BKS-REEL7

Overview

The ADR550BKS-REEL7 is a high precision shunt voltage reference manufactured by Analog Devices Inc. It provides a fixed 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 3-Lead SC70 package.

Feature Summary

• Ultracompact 3-Lead SC70 package design for space-critical applications
• Low temperature drift of 40 ppm/°C (maximum) ensuring stability
• Initial accuracy of ±0.2% for high precision requirements
• Trim terminal allows adjustment of 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 'BKS' corresponds to the SC70 package and Grade B specifications when sourcing. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the supply voltage and bias resistor calculations accommodate the minimum 50 μA and maximum 15 mA operating current limits for stable regulation.

Selection Notes

Select this component for designs requiring a precise 5.0 V reference in a minimal footprint. The trim terminal offers flexibility to correct system errors without affecting temperature coefficients. Consider the dynamic output impedance and noise characteristics relative to the application's sensitivity requirements.

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 concepts to produce stable references suitable for data acquisition components. The series is designed to operate without external compensation capacitors while remaining stable with any capacitive load.

Replacement Considerations

Pin compatible with LM4040/LM4050.
