ADR530BKS-REEL7

Overview

The ADR530BKS-REEL7 is a high precision shunt voltage reference from Analog Devices, housed in an ultracompact 3-Lead SC70 package. It provides a nominal output voltage of 3.0 V with Grade B initial accuracy of ±0.2% and a maximum temperature coefficient of 40 ppm/°C over the industrial range of −40°C to +85°C. The device operates within a current range of 50 μA to 15 mA and features low output noise of 22 μV p-p (0.1 Hz to 10 Hz). It includes a trim terminal for adjusting the output voltage by ±0.5% without affecting the temperature coefficient.

Feature Summary

• Ultracompact 3-Lead SC70 package designed for space-critical applications
• Low temperature drift of 40 ppm/°C with initial accuracy better than ±0.2%
• Trim terminal allows adjustment of output voltage over a ±0.5% range
• Operates without requiring an external compensation capacitor

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm the package type and compliance status. The 'KS' designation indicates the 3-Lead SC70 package, while 'Z' denotes RoHS compliance. Confirm that the reel quantity matches project requirements. Ensure the operating environment stays within the specified industrial temperature range of −40°C to +85°C for guaranteed performance.

Selection Notes

Select this component when a precise 3.0 V reference is required in a minimal footprint. The Grade B variant offers tighter accuracy and lower drift compared to Grade A. Consider the trim capability if system-level calibration is needed to compensate for board-level errors. Ensure the bias resistor selection keeps the operating current between 50 μA and 15 mA under all supply and load conditions.

Part Context

This part belongs to the ADR520/ADR525/ADR530/ADR540/ADR550 family of high precision shunt voltage references. These devices utilize band gap technology to achieve stable performance across varying temperatures. The series is designed to replace standard references like the LM4040/LM4050 while offering improved temperature coefficients and smaller packaging options for modern electronics.

Replacement Considerations

Pin compatible with LM4040/LM4050.
