ADR392ART-REEL7

Overview

The ADR392ART-REEL7 is a micropower, low noise precision voltage reference from the ADR39x family, manufactured by Analog Devices Inc. It provides a fixed output voltage of 4.096 V with an initial accuracy of ±6 mV and a temperature coefficient of 25 ppm/°C (A grade). The device operates within a supply voltage range of 4.3 V to 15 V and delivers up to 5 mA of output current. It features a shutdown mode with a maximum supply current of 3 μA and requires no external capacitors for stability.

Feature Summary

• Patented temperature drift curvature correction techniques achieve low temperature drift in a compact TSOT package.
• Advanced design eliminates the need for external capacitors, reducing board space and system cost.
• Includes a shutdown feature compatible with TTL/CMOS logic levels to minimize power consumption.

Applications

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

Procurement Notes

Verify the specific ordering suffix ART against the manufacturer's official documentation to confirm package type and reel specifications. Confirm that the component meets all required electrical parameters for your application before procurement. Check for any discontinuance notices or lifecycle status updates directly from Analog Devices to ensure long-term availability.

Selection Notes

Select this component when a stable 4.096 V reference is needed in space-constrained designs. The A grade offers a 25 ppm/°C temperature coefficient suitable for general precision applications. Ensure the input voltage remains at least 300 mV above the output voltage to maintain regulation. Consider the shutdown pin functionality if power management is critical for the system.

Part Context

This part belongs to the ADR39x series of micropower voltage references, which includes variants with different output voltages such as 2.048 V, 2.5 V, and 5 V. The family shares common architectural features like low dropout capability and ultralow output noise. The ADR392 specifically targets applications requiring a 4.096 V reference standard.

Replacement Considerations

Direct replacements include other parts within the ADR39x family with matching output voltages, such as the ADR392BUJZ-REEL7 for B grade performance. Verify pin compatibility and thermal characteristics when substituting.
