MAX6018BEUR16+T

Overview

The MAX6018BEUR16+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 ±0.4%. The device operates from an input voltage range of 1.8V to 5.5V, supporting a maximum load current of 1mA and consuming a maximum quiescent supply current of 5μA. It features a low dropout voltage of 200mV at full load and a temperature coefficient of 50ppm/°C. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low power consumption with supply current virtually independent of input voltage
• Capable of sourcing and sinking up to 1mA of load current
• Operates with a minimum dropout voltage of 200mV
• Requires no external resistors for operation

Applications

• Two-cell alkaline battery monitoring systems
• Battery-operated equipment
• Hand-held devices
• Data-acquisition systems
• Industrial and process-control systems

Procurement Notes

Verify the specific suffix 'EUR16' confirms the 1.6V output voltage and B-grade ±0.4% accuracy. Ensure the '+T' designation matches the required tape-and-reel packaging format. Confirm RoHS compliance status if restricted materials are prohibited in your assembly process. Cross-reference the manufacturer's latest datasheet revision to ensure all electrical characteristics remain unchanged.

Selection Notes

Select this component when a stable 1.6V reference is required in space-constrained designs using a SOT23-3 footprint. It is suitable for applications where minimizing static power draw is critical, such as portable or battery-powered instrumentation. Consider the ±0.4% initial accuracy and 50ppm/°C drift specifications against system tolerance requirements before finalizing the design.

Part Context

This part belongs to the MAX6018 family of precision bandgap voltage references manufactured by Analog Devices (Maxim Integrated). The series offers multiple fixed output voltages including 1.2V, 1.6V, 1.8V, and 2.048V. The BEUR16 variant specifically denotes the B-grade accuracy tier and the 1.6V output option within the standard surface-mount product line.

Replacement Considerations

MAX6018AEUR16+T: Offers higher initial accuracy of ±0.2% compared to the B-grade ±0.4%, while maintaining identical pinout, package, and electrical performance parameters.
