ADR366WAUJZ-REEL7

Overview

The ADR366WAUJZ-REEL7 is a precision band gap voltage reference providing a fixed 3.3 V output. It features a temperature coefficient of 9 ppm/°C and an initial accuracy of ±4 mV (±0.125%). The device operates with a maximum quiescent current of 190 µA and supports sourcing up to 5 mA and sinking up to 1 mA. It functions within a supply range of 3.6 V to 15 V, requiring a minimum dropout voltage of 300 mV. The component is housed in a TSOT-23-5 package and is qualified for automotive applications.

Feature Summary

• Offers sink/source capability allowing bidirectional load current handling without external components.
• Utilizes proprietary curvature correction techniques to achieve low temperature drift in a compact package.
• Eliminates the need for external capacitors for stability, reducing board space and system cost.

Applications

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

Procurement Notes

Verify the specific suffix 'R2' or 'REEL7' against the manufacturer's official ordering guide, as these indicate packaging variations that do not alter electrical function. Confirm the B-grade specification (9 ppm/°C) matches design requirements. Check for discontinuance notices or lifecycle status updates directly from Analog Devices documentation before finalizing procurement plans.

Selection Notes

Select this component when a stable 3.3 V reference is required in space-constrained designs. It is suitable for applications needing both sourcing and sinking currents. Ensure the input voltage provides at least 300 mV headroom above the output. Consider the 190 µA quiescent current for battery life calculations and verify thermal dissipation limits if operating near maximum junction temperatures.

Part Context

This part belongs to the ADR36x family of micropower, low dropout voltage references manufactured by Analog Devices. The family includes variants with different output voltages such as 2.048 V, 2.5 V, 3.0 V, 4.096 V, and 5.0 V. All members share similar architectural features, including low noise and high precision, but differ in nominal output voltage and specific grading options.

Replacement Considerations

Direct substitutes within the same family include ADR366AUJZ-R2 and ADR366BUJZ-R2, which offer identical 3.3 V outputs with varying temperature coefficients (25 ppm/°C vs. 9 ppm/°C). Other family members like ADR365WAUJZ-REEL7 provide different voltages and should only be considered if voltage adjustment is feasible.
