MAX6064BEUR-T

Overview

The MAX6064BEUR-T is a precision, micropower, low-dropout voltage reference from the MAX6061–MAX6068 family. It provides a fixed output voltage of 4.096V with an initial accuracy of ±0.4% and a maximum temperature coefficient of 30ppm/°C. The device operates within an input voltage range of (VOUT + 200mV) 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 'B' indicates the ±0.4% accuracy grade rather than the higher precision 'A' grade. Confirm the 'EUR' designation corresponds to the SOT-23-3 surface-mount package. Ensure the '+T' suffix aligns with the required reel packaging format for automated assembly processes.

Selection Notes

Select this part when a stable 4.096V reference is needed in space-constrained designs without external components. It is suitable for applications requiring low dropout voltage and minimal power consumption. Consider the ±0.4% tolerance if tighter accuracy is not critical, as it offers a cost-effective alternative to the ±0.2% variant.

Part Context

This component belongs to the MAX6061–MAX6068 series of precision voltage references manufactured by Analog Devices / Maxim Integrated. The family shares common features such as micropower operation, low dropout characteristics, and the compact SOT-23-3 package. Variants differ primarily by output voltage and initial accuracy grades.

Replacement Considerations

The MAX6064AEUR-T serves as a direct functional substitute offering improved initial accuracy of ±0.2% while maintaining identical pinout and electrical specifications.

FAQ

Does the MAX6064BEUR-T require an external capacitor for stability?

No, the device is internally compensated and does not require an external compensation capacitor for frequency stability.

What is the minimum input voltage required for proper operation?

The minimum input voltage is VOUT + 200mV, which equals approximately 4.296V for the 4.096V output version.
