MAX6165BESA+

Overview

The MAX6165BESA+ is a precision, low-dropout, micropower voltage reference from the MAX6161–MAX6168 family. It provides a fixed output voltage of 5.0V with an initial accuracy of ±4mV and a maximum temperature coefficient of 10ppm/°C. The device operates within an input voltage range of 5.2V to 12.6V and draws a typical quiescent supply current of 100µA. It can source up to 5mA or sink 2mA of load current while maintaining stability without requiring external compensation capacitors.

Feature Summary

• Features proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision.
• Offers supply current virtually independent of input voltage to maximize efficiency in battery-powered systems.
• Eliminates the need for external compensation capacitors, saving board space in compact designs.

Applications

• Analog-to-Digital Converters (ADCs)
• Portable Battery-Powered Systems
• Precision +3V/+5V Systems

Procurement Notes

Verify the specific suffix 'B' indicates the required initial accuracy and temperature coefficient specifications. Confirm the package type matches the design footprint requirements. Ensure the input voltage supply meets the minimum dropout requirements for reliable operation across the specified temperature range.

Selection Notes

Select this component when a stable 5.0V reference is needed with minimal power consumption. Consider the ±4mV accuracy and 10ppm/°C drift limits against system error budgets. Evaluate the 5mA sourcing capability against load requirements to ensure adequate drive strength without exceeding thermal limits.

Part Context

This part belongs to the MAX6161–MAX6168 series of precision voltage references manufactured by Analog Devices / Maxim Integrated. The series shares common architectural features including micropower operation and low-dropout characteristics, differentiated primarily by their fixed output voltage options ranging from 1.25V to 5.0V.

Replacement Considerations

Direct replacements within the same family include other MAX616x variants with different output voltages if the system allows voltage adjustment. Verify pin compatibility and electrical specifications before substituting with non-series components.
