MAX6067BEUR-T

Overview

The MAX6067BEUR-T is a precision, micropower, low-dropout voltage reference from the MAX6061–MAX6068 series. It provides a fixed output voltage of 4.5V with an initial accuracy of ±0.4% and a maximum temperature coefficient of 30ppm/°C. The device operates within an input voltage range of 4.7V to 12.6V and draws a typical quiescent supply current of 90µA. It can source up to 5mA or sink up to 2mA of load current. The component is housed in a 3-pin SOT-23 package and functions reliably across an extended temperature range of -40°C to +85°C.

Feature Summary

• Proprietary curvature-correction circuit combined with laser-trimmed thin-film resistors ensures high precision and stability.
• Series-mode architecture eliminates the need for external biasing resistors required by conventional shunt references.
• Internally compensated design removes the requirement for external compensation capacitors, saving board space.
• Supply current remains virtually independent of the input supply voltage, maximizing efficiency in battery-operated systems.

Applications

• Analog-to-Digital Converters (ADCs)
• Portable Battery-Powered Systems
• Precision 3V/5V Systems

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm that the 'B' grade designation corresponds to the required ±0.4% initial accuracy specification for your application. Ensure the input voltage supply stays within the specified minimum dropout requirements relative to the 4.5V output. Check for RoHS compliance documentation if environmental regulations apply to your manufacturing process.

Selection Notes

Select this part when a stable 4.5V reference is needed in a compact SOT-23 footprint. It is suitable for applications requiring low quiescent current and high line regulation without external components. Consider the 30ppm/°C temperature coefficient limit for wide-temperature environments. Evaluate the 5mA sourcing capability against peak load demands to ensure adequate drive strength.

Part Context

This component belongs to the MAX6061–MAX6068 family of precision voltage references manufactured by Analog Devices / Maxim Integrated. The family shares common internal architectures and packaging options but varies in fixed output voltages ranging from 1.25V to 5V. The MAX6067 variant specifically targets the 4.5V output segment of this portfolio.

Replacement Considerations

Other members of the MAX6061–MAX6068 series share identical pinouts and packages. Verify that alternative part numbers provide the same 4.5V output voltage and meet the required accuracy grades for direct substitution.
