ADR366AUJZ-REEL7

Overview

The ADR366AUJZ-REEL7 is a precision band gap voltage reference providing a nominal output of 3.300 V with an initial accuracy of ±8 mV maximum and a temperature coefficient of 25 ppm/°C. It operates within a supply voltage range of 3.6 V to 15 V, delivering a sourcing current of up to 5 mA and sinking up to 1 mA. The device features ultralow output noise of 9.3 µV p-p from 0.1 Hz to 10 Hz and requires no external capacitors for stability. Quiescent current is limited to 190 µA maximum across the operating temperature range of −40°C to +125°C.

Feature Summary

• Proprietary curvature correction techniques achieve low temperature drift in a compact TSOT package.
• Advanced design eliminates the need for external input or output capacitors, reducing board space.
• Band gap architecture referenced to the output attenuates ground line noise effectively.

Applications

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

Procurement Notes

Verify the specific grade suffix against the datasheet ordering guide to confirm the exact temperature coefficient and accuracy specifications. Confirm that the REEL7 packaging designation matches the required quantity format for your assembly line. Ensure the component meets RoHS compliance requirements for your target market regulations before finalizing procurement.

Selection Notes

Select this component when a stable 3.3 V reference is needed with minimal external components. The A grade offers wider availability but higher drift compared to B grade options. Consider the 300 mV dropout voltage requirement relative to your minimum supply rail. Evaluate the 190 µA quiescent current impact on total system power consumption during active operation.
