MAX6018AEUR16+T

Overview

The MAX6018AEUR16+T is a precision micropower voltage reference in a SOT23-3 package. It provides a fixed output of 1.6V with an initial accuracy of ±0.2%. The device operates from an input voltage range of 1.8V to 5.5V, consuming a maximum quiescent supply current of 5µA at +25°C and 6µA across the full temperature range. It features a low dropout voltage of 200mV at 1mA load and supports continuous sourcing and sinking of up to 1mA. The unit maintains stability with capacitive loads between 100pF and 1µF.

Feature Summary

• Ultra-low supply current that remains virtually independent of input voltage variations
• Low-dropout operation enabling functionality near battery depletion levels
• High initial accuracy and low temperature drift for stable reference performance
• Compact three-terminal surface-mount packaging

Applications

• Two-cell alkaline battery-operated systems
• End-of-life battery monitoring circuits
• Hand-held portable equipment
• Data-acquisition systems
• Industrial and process-control instrumentation

Procurement Notes

Verify the specific suffix 'EUR16' corresponds to the 1.6V output variant and 'A' grade for ±0.2% accuracy. Confirm the '+T' designation indicates tape-and-reel packaging. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and revision status before procurement.

Selection Notes

Select this component when a fixed 1.6V reference is required within a tight space constraint provided by the SOT23-3 package. It is suitable for applications demanding minimal power consumption below 6µA. Consider the 200mV dropout characteristic for single-supply designs operating close to the minimum input threshold. Verify that the ±0.2% initial accuracy meets the system's calibration requirements without external trimming.

Part Context

This device belongs to the MAX6018 family of precision voltage references manufactured by Analog Devices (Maxim Integrated). The family includes variants with different output voltages (1.2V, 1.8V, 2.048V) and accuracy grades (A and B). All members share the same low-power architecture and SOT23 form factor, designed for battery-powered and portable electronic applications requiring stable voltage regulation.

Replacement Considerations

MAX6018BEUR16+T offers identical electrical characteristics but with a relaxed ±0.4% initial accuracy grade.
