MAX6101EUR

Overview

The MAX6101EUR is a precision series voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 1.25V with an initial accuracy of ±0.4%. The device operates within a supply voltage range up to 5.5V and draws a maximum quiescent current of 5µA. It features a temperature coefficient of 75ppm/°C and supports a load current of 5mA. The component is housed in a compact SOT-23-3 package, suitable for surface-mount installation, and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides a stable 1.25V fixed output voltage via a sub-1V bandgap reference architecture.
• Delivers low output impedance for accurate signal conditioning in sensitive circuits.
• Operates with minimal power consumption, extending battery life in portable applications.

Applications

• Portable instrumentation requiring precise voltage references
• Battery-powered measurement systems
• Data acquisition channels

Procurement Notes

Verify the specific suffix (e.g., EUR vs. EUR+T) against the manufacturer's datasheet to confirm packaging format and RoHS compliance status. Confirm availability through authorized distributors as supply constraints may apply. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component when a fixed 1.25V reference is required in space-constrained designs. The SOT-23-3 package offers a small footprint compared to larger alternatives. Consider the 75ppm/°C temperature coefficient for environmental stability requirements. Verify that the 5mA load capability meets the downstream circuit demands without exceeding the device's limits.

Part Context

The MAX6101 belongs to Maxim Integrated's family of micropower voltage references designed for low-voltage operation. This series emphasizes high accuracy and low power consumption, making it suitable for modern portable electronics. The EUR designation indicates a specific package and temperature grade within the broader MAX610x product line.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX610x family or other 1.25V references from Analog Devices. Verify that alternative components match the 1.25V output, ±0.4% accuracy, and SOT-23-3 package dimensions before integration.
