ADR02AUJZ-REEL7

Overview

The ADR02AUJZ-REEL7 is a precision series voltage reference manufactured by Analog Devices Inc., housed in a TSOT-23-5 surface-mount package. It provides a fixed output voltage of 5 V with an initial accuracy of ±0.1%. The device operates within an extended temperature range from -40°C to +125°C and features a low temperature coefficient of 3 PPM/°C. It supports a maximum input voltage of 36 V and can deliver a maximum shunt current of 10 mA while consuming only 1 mA of supply current.

Feature Summary

• Delivers high-precision fixed voltage output with tight initial accuracy tolerance
• Maintains stable performance across wide industrial temperature ranges
• Operates efficiently with minimal quiescent current consumption

Applications

• High-resolution analog-to-digital converter (ADC) reference sources
• Precision data acquisition systems requiring stable voltage baselines
• Calibration equipment for measurement instrumentation

Procurement Notes

Verify the specific suffix REEL7 confirms tape-and-reel packaging configuration before ordering. Ensure the TSOT-23-5 footprint matches your PCB layout constraints. Confirm that the 5 V output aligns with your system requirements, as other variants in the ADR02 series offer different voltages. Check RoHS compliance status for environmental regulations.

Selection Notes

Select this component when a compact form factor is required alongside high precision. The 3 PPM/°C temperature coefficient makes it suitable for applications demanding long-term stability without external trimming. Compare against lower-accuracy alternatives if cost is a primary driver, or higher-performance XFET devices if ultra-low noise is critical.

Part Context

This part belongs to the ADR02 series of precision bandgap voltage references from Analog Devices. The series is designed for applications requiring small size and high accuracy. The AUJZ suffix indicates the specific package type and temperature grade, distinguishing it from other pin-compatible or functional variants within the broader product line.

Replacement Considerations

Direct substitutes include other ADR02 series parts with identical 5 V output and TSOT-23-5 packaging, such as ADR02AUJZ. Verify that any replacement maintains the same 3 PPM/°C temperature coefficient and ±0.1% initial accuracy to ensure circuit compatibility.
