ADR293GR-REEL

Overview

The ADR293GR-REEL is a precision series voltage reference manufactured by Analog Devices Inc., delivering a fixed output of 5 V. It operates within an extended temperature range from -40 °C to +125 °C and features a low temperature coefficient of 3 PPM/°C. The device draws a typical supply current of 15 µA, supporting a maximum shunt current of 5 mA. Packaged in an SOIC-8 surface-mount format and supplied in reel packaging, it is designed for applications requiring stable, low-noise, and micropower voltage references.

Feature Summary

• Provides a stable 5 V reference with high accuracy and low noise characteristics suitable for precision analog circuits.
• Operates efficiently at extremely low quiescent currents, making it ideal for battery-powered and portable equipment.
• Maintains performance across a wide industrial temperature range with minimal drift due to a low temperature coefficient.

Applications

• Portable equipment power supplies
• Handheld meters
• Battery-powered instrumentation

Procurement Notes

Verify the specific suffix 'GR' against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint and reflow profile requirements. Confirm availability status as distribution channels may list limited stock or restricted supply conditions for this component.

Selection Notes

Select this component when a fixed 5 V reference is required with ultra-low power consumption and high precision. Compare against other ADR29x family members if different output voltages are needed. Ensure the input voltage exceeds the minimum dropout requirement and that the load current remains within the specified shunt limits to maintain regulation.

Part Context

This part belongs to the ADR29x series of micropower precision voltage references from Analog Devices. The series includes variants with different output voltages such as 2.5 V (ADR291) and 4.096 V (ADR292), all sharing similar low-power and high-accuracy characteristics. These devices are commonly used in data acquisition systems and sensor interfaces.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADR29x family or comparable parts from other manufacturers offering 5 V output, 3 PPM/°C stability, and SOIC-8 packaging. Verify electrical parameters match exactly before substitution.
