MAX6061BEUR-T

Overview

The MAX6061BEUR-T is a precision, micropower, low-dropout voltage reference in a 3-pin SOT23 package. It provides a fixed output of 1.248V with an initial accuracy of ±0.32% and a maximum temperature coefficient of 20ppm/°C. The device operates from an input voltage range of 2.5V to 12.6V, drawing a typical quiescent supply current of 90µA. It can source up to 5mA and sink up to 2mA of load current. Specifications are guaranteed over the extended temperature range of -40°C to +85°C.

Feature Summary

• Proprietary curvature-correction circuit and laser-trimmed thin-film resistors ensure high precision and stability.
• Internally compensated design eliminates the need for external compensation capacitors, saving board space.
• Supply current remains virtually independent of the supply voltage, maximizing efficiency in battery-operated systems.
• Capable of sourcing 5mA and sinking 2mA without requiring an external resistor.

Applications

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

Procurement Notes

Verify the specific suffix 'B' indicates the ±0.32% accuracy grade against the datasheet selector guide. Confirm the 'EUR' designation corresponds to the SOT23-3 surface-mount package. Ensure the '+T' suffix matches the required reel or cut tape packaging format for your assembly process. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm current production status.

Selection Notes

Select this component when a fixed 1.248V reference is required with tight initial accuracy. The low dropout voltage allows operation close to the output level. Consider the 90µA quiescent current for power-sensitive designs. Verify that the 5mA source and 2mA sink capabilities meet the load requirements. Ensure the operating environment stays within the specified -40°C to +85°C temperature range.

Part Context

This device belongs to the MAX6061–MAX6068 family of precision voltage references. All members share similar internal architectures, including curvature correction and low quiescent current. The MAX6061 variant specifically offers the 1.248V output option. The family is designed for space-critical applications due to the compact SOT23-3 package.

Replacement Considerations

Other members of the MAX6061–MAX6068 family may serve as alternatives if different output voltages are acceptable. Verify that any substitute maintains the required accuracy grade and package type. Check for compatibility in terms of input voltage range and load current capabilities before implementation.
