ADR392AUJZ-REEL7

Overview

The ADR392AUJZ-REEL7 is a micropower, low noise precision voltage reference providing a fixed output of 4.096 V. It features an initial accuracy of ±6 mV and a temperature coefficient of 25 ppm/°C across the operating range. The device operates with a supply current of 140 μA maximum and supports up to 5 mA load current. It includes a shutdown function reducing current to 3 μA and requires no external capacitors for stability.

Feature Summary

• Integrated shutdown mode compatible with TTL/CMOS logic levels
• Patented curvature correction for low temperature drift
• Eliminates need for external bypass capacitors
• Capable of driving capacitive loads up to 10 μF

Applications

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

Procurement Notes

Verify the specific suffix 'R2' against the official datasheet ordering guide, as it may indicate a specific packaging or reel configuration distinct from standard tape-and-reel variants. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the TSOT-23-5 package dimensions align with your PCB footprint design constraints before finalizing procurement.

Selection Notes

Select this component when a stable 4.096 V reference is required in space-constrained designs. The A grade offers a wider temperature coefficient compared to the B grade but maintains high precision. Consider the low dropout voltage for battery applications where input voltage approaches the output level. Verify that the 140 μA quiescent current fits within the system power budget.

Part Context

This part belongs to the ADR39x family of band gap voltage references manufactured by Analog Devices. The family includes the ADR391 (2.5 V), ADR392 (4.096 V), and ADR395 (5 V) variants. All share similar architectural features, including micropower operation and compact packaging, designed for high-precision applications requiring minimal board space.

Replacement Considerations

ADR392BUJZ-REEL7: Offers improved temperature coefficient (9 ppm/°C) and tighter initial accuracy (±5 mV).

FAQ

Is an external capacitor required for stability?

No, the ADR392 does not require external capacitors for circuit stability under any load condition.

How is the shutdown pin configured if not used?

If the shutdown feature is not utilized, the SHDN pin must be connected directly to the VIN pin.
