MAX6163AESA

Overview

The MAX6163AESA is a precision, micropower, low-dropout voltage reference from the MAX6161–MAX6168 family. It provides a fixed output voltage of 3.000V with an initial accuracy of ±2mV and a maximum temperature coefficient of 5ppm/°C. The device operates within an input voltage range of VOUT + 0.2V to 12.6V, drawing a typical quiescent supply current of 100µA that remains virtually independent of the supply voltage. It can source up to 5mA or sink 2mA of load current without requiring external compensation capacitors.

Feature Summary

• Features proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high stability
• Offers supply-independent ultra-low quiescent current to maximize efficiency in battery-operated systems
• Eliminates the need for external compensation capacitors, saving valuable board area
• Capable of sourcing 5mA and sinking 2mA of load current while maintaining low dropout voltage

Applications

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

Procurement Notes

Verify the specific suffix and package code against the manufacturer's latest ordering information to ensure correct RoHS compliance and pin configuration. Confirm availability status as distribution channels may vary. Cross-reference the electrical characteristics table for the exact A-grade specifications regarding initial accuracy and temperature drift before finalizing procurement decisions.

Selection Notes

Select this component when a stable 3.000V reference is required with minimal power consumption. It is suitable for space-constrained designs due to the lack of external capacitor requirements. Ensure the input voltage stays within the specified dropout limits relative to the 3.000V output. Consider the ±2mV initial accuracy and 5ppm/°C temperature coefficient for precision applications.

Part Context

This part belongs to the MAX6161–MAX6168 series of precision voltage references manufactured by Analog Devices / Maxim Integrated. The family shares common architectural features including BiCMOS processing and SO-8 packaging. Variants within the series differ primarily by their fixed output voltage options, ranging from 1.25V to 5.0V, while maintaining similar performance metrics for noise, line regulation, and load regulation.

Replacement Considerations

Direct functional substitutes within the same family include MAX6163B for looser tolerance requirements. Other voltage levels in the series such as MAX6166 (2.5V) or MAX6164 (4.096V) share identical pinouts but provide different reference voltages.
