MAX6100EUR

Overview

The MAX6100EUR is a fixed-output series voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a nominal output voltage of 1.8V with a tight tolerance of ±0.4%. The device operates within an input voltage range of 2.5V to 12.6V and draws a supply current of 125µA. It supports a maximum output current of 5mA and features a temperature coefficient of 75ppm/°C. Noise performance is specified at 22µVp-p from 0.1Hz to 10Hz and 25µVrms from 10Hz to 10Hz. The component is housed in a SOT-23-3 surface-mount package and functions reliably across a junction temperature range of -40°C to 85°C.

Feature Summary

• Fixed 1.8V output with high precision accuracy
• Low quiescent current consumption for battery efficiency
• Compact three-terminal surface-mount packaging

Applications

• Portable instrumentation requiring stable reference voltages
• Battery-powered measurement systems
• Data acquisition systems needing low-noise references

Procurement Notes

Verify the specific suffix against official documentation to confirm exact electrical tolerances and thermal characteristics, as variations exist within the family. Ensure the ordering part number matches the required output voltage and package type. Confirm RoHS compliance status through the manufacturer's latest certification documents before procurement integration.

Selection Notes

Select this component when a precise 1.8V reference is required in space-constrained designs. The low supply current makes it suitable for energy-efficient applications. Verify that the input voltage remains within the specified operational window to maintain regulation. Consider the thermal environment to ensure operation stays within the rated temperature limits for long-term stability.

Part Context

This component belongs to the MAX6100-MAX6107 series of micropower, low-dropout voltage references. These devices are designed to provide accurate reference voltages in small packages. The series shares common architectural features such as bandgap reference technology and similar pinouts, differing primarily in output voltage settings and specific noise specifications.

Replacement Considerations

Compatible substitutes include other members of the MAX6100 series with identical or compatible output voltages, such as the MAX6101 or MAX6102, provided the voltage level meets circuit requirements. Cross-referencing datasheets is necessary to verify pin compatibility and electrical parameter alignment.
