MAX6021BEUR-TG097

Overview

The MAX6021BEUR-TG097 is a precision, low-power, low-dropout voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 2.048V and is housed in a miniature SOT-23-3 surface-mount package. The device features a proprietary curvature-correction circuit and laser-trimmed thin-film resistors to achieve an initial accuracy better than 0.2% and a temperature coefficient of less than 15ppm/°C. It operates within an extended temperature range from -40°C to +85°C.

Feature Summary

• Utilizes proprietary curvature-correction circuitry for enhanced stability
• Employs laser-trimmed thin-film resistors for high initial accuracy
• Designed as a low-dropout regulator for efficient power usage

Applications

• Portable instrumentation systems requiring stable reference voltages
• Battery-powered measurement devices with strict power constraints
• Data acquisition systems needing precise analog-to-digital conversion references

Procurement Notes

Verify the specific suffix TG097 against official manufacturer documentation to confirm tape-and-reel specifications or lot-specific attributes. Ensure compatibility with RoHS directives if lead-free status is required, as some sources indicate non-compliance for certain variants. Cross-reference the part number with authorized distributors to confirm current availability and authenticity.

Selection Notes

Select this component when a fixed 2.048V reference is required in space-constrained designs. The SOT-23-3 package minimizes board area while maintaining precision. Consider the low quiescent current for battery-operated applications. Verify that the 0.2% initial accuracy and <15ppm/°C drift meet the system's error budget requirements over the specified temperature range.

Part Context

This part belongs to the MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/MAX6045/MAX6050 family of precision voltage references. These devices share common architectural features such as curvature correction and micropower operation but differ in output voltage options and packaging configurations. The MAX6021 specifically offers the 2.048V output option within this series.

Replacement Considerations

Consult official substitution guides for compatible parts within the same Maxim Integrated/Analog Devices voltage reference portfolio. Verify pinout compatibility and electrical parameter equivalence before replacing.
