ADR364BUJZ-R2

Overview

The ADR364BUJZ-R2 is a micropower, low dropout voltage reference providing a fixed 4.096 V output in a compact TSOT-5 package. It features B-grade initial accuracy of ±4 mV and a temperature coefficient of 9 ppm/°C across the −40°C to +125°C range. The device draws a maximum quiescent current of 190 µA and supports an output sourcing current of 5 mA and sinking current of 1 mA. It operates with a minimum dropout voltage of 300 mV and exhibits ultralow output voltage noise of 11 µV p-p from 0.1 Hz to 10 Hz.

Feature Summary

• Proprietary temperature drift curvature correction techniques enable low temperature drift within a small footprint.
• Advanced design eliminates the need for external capacitors, reducing board space and system cost.
• Band gap architecture referenced to the output attenuates ground line noise effects.

Applications

• Battery-powered instruments
• Portable medical instruments
• Data acquisition systems
• Industrial process controls

Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm packaging configuration. Confirm that the component meets all required environmental specifications for the intended operating temperature range. Ensure input voltage headroom satisfies the minimum dropout requirements for the specific load conditions.

Selection Notes

Select this component when a stable 4.096 V reference is required in space-constrained designs. The B-grade specification provides tighter accuracy than the A-grade variant. Consider the low quiescent current for battery-operated applications where power efficiency is critical. Verify that the supply voltage allows for the specified 300 mV dropout margin under maximum load.

Part Context

This part belongs to the ADR360/ADR361/ADR363/ADR364/ADR365/ADR366 family of precision band gap voltage references manufactured by Analog Devices Inc. The family shares common architectural features including micropower operation and low dropout characteristics, differentiated primarily by output voltage levels and grade-specific performance parameters.

Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Do not assume functional equivalence based on generic family similarities without verifying specific electrical parameter alignment.
