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 (VOUT + 200mV) to 12.6V and draws a typical quiescent supply current of 100μA. It can source up to 5mA or sink 2mA of load current without requiring external resistors or compensation capacitors.

Feature Summary

• Features proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high stability.
• Offers supply current virtually independent of supply voltage, maximizing efficiency in battery-operated systems.
• Internally compensated design eliminates the need for external compensation capacitors.
• Capable of sourcing 5mA and sinking 2mA load currents 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 'A' for ±2mV initial accuracy and 5ppm/°C temperature coefficient against the datasheet selector guide. Confirm the package type is 8-pin SO and the operating temperature range is -40°C to +85°C. Ensure the ordering code matches the required output voltage of 4.096V. Check for RoHS compliance status indicated by the '+' suffix.

Selection Notes

Select this component when a stable 4.096V reference is needed with minimal board space due to the lack of external components. Consider the 100μA quiescent current for power-sensitive designs. Evaluate the 5mA source capability against load requirements. Compare line and load regulation specifications if high precision under varying conditions is critical.

Part Context

This part belongs to the MAX6161–MAX6168 family of precision voltage references manufactured by Analog Devices Inc./Maxim Integrated. The family shares common features such as micropower operation, low dropout, and high output current. Variants differ primarily in output voltage options ranging from 1.25V to 5V and accuracy grades.

Replacement Considerations

Other members of the MAX6161–MAX6168 family may serve as alternatives if different output voltages are acceptable. Verify pin compatibility and electrical specifications before substitution.
