MAX6164AESA+T

Overview

The MAX6164AESA+T is a precision, low-dropout, micropower voltage reference from the MAX6161–MAX6168 series. It provides a fixed output voltage of 4.096V with an initial accuracy of ±2mV and a maximum temperature coefficient of 5ppm/°C. The device operates within an input voltage range of 4.296V 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.
• Delivers high output current capability with minimal dropout voltage under load conditions.
• Operates with supply current virtually independent of input voltage variations.
• Internally compensated design eliminates the need for external frequency-stability capacitors.

Applications

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

Procurement Notes

Verify the specific suffix 'A' confirms the ±2mV initial accuracy and 5ppm/°C temperature coefficient variant. Confirm the '+T' designation indicates tape-and-reel packaging rather than tube. Ensure the SO-8 package code matches the required footprint. Check RoHS compliance status if environmental regulations apply to the assembly process.

Selection Notes

Select this component when a stable 4.096V reference is required with tight initial accuracy specifications. Consider the low quiescent current for battery-operated designs where power efficiency is critical. Evaluate the dropout voltage requirements against the minimum available supply voltage to ensure regulation is maintained under all operating conditions.

Part Context

This part belongs to the MAX6161–MAX6168 family of precision voltage references manufactured by Analog Devices / Maxim Integrated. The family shares common architectural features including micropower operation and low-dropout performance. Variants differ primarily in their fixed output voltage levels, ranging from 1.25V to 5V, while maintaining similar electrical characteristics and package options.

Replacement Considerations

Direct functional substitutes within the same family include MAX6164BESA+T, which offers slightly lower initial accuracy but similar temperature stability. Other voltage levels in the series such as MAX6166AESA+T (2.5V) or MAX6167AESA+T (4.5V) may be considered if different reference voltages are acceptable for the application design.
