MAX6066AEUR-T

Overview

The MAX6066AEUR-T is a precision, micropower, low-dropout voltage reference featuring a fixed 2.5V output. It operates within an input voltage range of 2.7V to 12.6V and maintains an initial accuracy of ±0.2% with a maximum temperature coefficient of 20ppm/°C. The device draws a typical quiescent supply current of 90µA and can source up to 5mA or sink 2mA of load current. It is housed in a compact 3-pin SOT-23 package and functions reliably across an extended temperature range of -40°C to +85°C.

Feature Summary

• Proprietary curvature-correction circuitry ensures high precision and stability
• Laser-trimmed thin-film resistors provide tight initial accuracy limits
• Internally compensated design eliminates the need for external compensation capacitors
• Supply current remains virtually independent of the input supply voltage

Applications

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

Procurement Notes

Verify the specific suffix 'EUR' corresponds to the SOT-23-3 surface-mount package configuration. Confirm that the 'A' grade designation aligns with the required ±0.2% initial accuracy specifications. Ensure the '+T' tape-and-reel packaging format matches the intended automated assembly process requirements.

Selection Notes

Select this component when board space is constrained due to the small SOT-23-3 footprint. Choose this part for battery-operated applications requiring ultra-low quiescent current consumption. Opt for this reference where stable performance is needed without adding external capacitors to the layout.

Part Context

This device belongs to the MAX6061–MAX6068 family of precision voltage references manufactured by Analog Devices / Maxim Integrated. The family shares common internal architectures but varies in fixed output voltage options ranging from 1.25V to 5V. All members utilize the same three-terminal SOT-23 package form factor.

Replacement Considerations

Other members of the MAX6061–MAX6068 series may serve as functional substitutes if different output voltages are acceptable. Verify pin compatibility and thermal characteristics before substituting.
