MAX6164AESA

Overview

The MAX6164AESA 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.
• Offers supply current virtually independent of supply voltage to maximize efficiency in battery-operated systems.
• Internally compensated design eliminates the need for external frequency-stability capacitors.
• Capable of sourcing 5mA and sinking 2mA load currents with low dropout voltage characteristics.

Applications

• Analog-to-Digital Converters (ADCs)
• Portable Battery-Powered Systems
• Notebook Computers
• PDAs, GPS, DMMs
• Cellular Phones

Procurement Notes

Verify the specific suffix 'A' indicates the ±2mV initial accuracy and 5ppm/°C temperature coefficient variant. Confirm the package type matches the required SO-8 footprint. Check for lead-free/RoHS compliance status indicated by the '+' suffix if applicable. Ensure the input voltage supply meets the minimum dropout requirement relative to the 4.096V output.

Selection Notes

Select this component when a stable 4.096V reference is needed with minimal board space due to the lack of external capacitor requirements. Consider the 100μA quiescent current for power-sensitive designs. Verify that the application load does not exceed the 5mA sourcing or 2mA sinking limits. Compare against other series members if different voltage levels like 2.5V or 5V are acceptable.

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 BiCMOS process technology and 8-pin SO packaging. Variants differ primarily in their fixed output voltage options ranging from 1.25V to 5V and their specific accuracy grades.

Replacement Considerations

Other members of the MAX6161–MAX6168 series share identical pinouts and packages. Suitable substitutes include MAX6161AESA through MAX6168AESA depending on the required output voltage level. Cross-reference electrical specifications such as line regulation and noise performance to ensure compatibility with the existing circuit design.

FAQ

Does the MAX6164AESA require an external capacitor for stability?
