ADR395BUJZ-REEL7

Overview

The ADR395BUJZ-REEL7 is a micropower, low noise precision voltage reference from Analog Devices Inc., featuring a fixed 5 V output. It operates within an input voltage range of 5.3 V to 15 V and delivers up to 5 mA of output current with a maximum supply current of 140 µA. The device offers high initial accuracy of ±0.1% (±5 mV) and a low temperature coefficient of 9 ppm/°C. It incorporates ultralow output noise of 8 µV p-p in the 0.1 Hz to 10 Hz band and includes a shutdown mode drawing only 3 µA. Packaged in a compact TSOT-23-5 format, it supports operation across a wide temperature range of -40°C to +125°C.

Feature Summary

• Patented temperature drift curvature correction techniques enable low temperature coefficients in a compact footprint.
• Advanced design eliminates the need for external capacitors, reducing board space and system cost.
• Integrated shutdown feature allows for ultra-low power consumption when the device is not in use.
• Band gap architecture references the ideal zero temperature coefficient voltage to the output rather than ground.

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required grade and packaging configuration. Confirm the component meets RoHS compliance standards for your region. Ensure the supplier provides valid traceability documentation. Check for any recent Product Change Notifications regarding manufacturing site updates. Validate that the received parts match the specified package type and pinout.

Selection Notes

Select this component when a stable 5 V reference is required in space-constrained designs. It is suitable for applications demanding low quiescent current and minimal external components. Consider the B-grade specifications for tighter accuracy and lower temperature drift compared to the A-grade variant. Evaluate the dropout voltage requirements against the available supply headroom.

Part Context

This part belongs to the ADR39x family of micropower, low dropout voltage references, which also includes the ADR391 and ADR392 models. These devices share similar architectural features and performance characteristics but differ in their fixed output voltages. The family is designed for battery-operated applications requiring high precision and small size.
