ADR1500BKSZ-REEL

Overview

The ADR1500BKSZ-REEL7 is a low-cost, two-terminal shunt voltage reference providing an accurate 1.2875 V output. It operates within an input current range of 50 μA to 10 mA and maintains an initial accuracy of ±0.2% maximum. The device features a wideband noise of 20 μV rms (10 Hz to 10 kHz) and a temperature drift of 170 ppm/°C typical over the −40°C to +85°C specified range. It utilizes a compact SC-70 surface-mount package.

Feature Summary

• Provides stable 1.2875 V precision band gap reference
• Operates with minimum current as low as 50 μA
• Compact three-lead SC-70 surface-mount package

Applications

• Computer servers
• Battery-powered instrumentation
• Portable medical equipment
• Automotive systems

Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm package type and environmental compliance. Confirm that the REEL7 designation corresponds to the correct tape and reel quantity for manufacturing integration. Ensure compatibility with standard SMD assembly processes for the SC-70 footprint.

Selection Notes

Select this component when a fixed 1.2875 V reference is required in space-constrained designs. The low minimum operating current makes it suitable for battery-powered applications where quiescent power consumption must be minimized. Verify that the load current requirements fall within the 50 μA to 10 mA operational window.

Part Context

This part belongs to the ADR1500 series of micropower shunt voltage references manufactured by Analog Devices Inc. The series utilizes band gap technology to deliver high stability across varying temperatures and currents. The KS suffix indicates the specific SC-70 package option used for surface-mount assembly.
