MAX6164BESA+

Overview

The MAX6164BESA+ is a precision, low-dropout, micropower voltage reference providing a fixed output of 4.096V in an 8-pin SO package. It operates within an input voltage range from VOUT + 200mV to 12.6V and maintains an extended temperature range of -40°C to +85°C. The device features a maximum initial accuracy of ±2mV and a maximum temperature coefficient of 5ppm/°C. Typical quiescent supply current is 100μA, with the ability to source up to 5mA or sink 2mA of load current.

Feature Summary

• Utilizes proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high stability
• Operates with supply current virtually independent of input voltage variations
• Internally compensated design eliminates the need for external compensation capacitors
• Capable of sourcing 5mA and sinking 2mA without requiring external biasing resistors

Applications

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

Procurement Notes

Verify the specific suffix code against the manufacturer's selector guide to confirm the exact initial accuracy and temperature coefficient specifications required for the application. Confirm that the 8-pin SO package outline matches the target PCB footprint. Ensure the input voltage source can provide sufficient current during turn-on transients to guarantee reliable operation.

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 5mA source capability for driving moderate loads directly. Evaluate the line regulation performance relative to the expected input voltage fluctuations in the system to ensure it meets the precision requirements of the downstream circuitry.

Part Context

This part belongs to the MAX6161–MAX6168 family of precision, micropower, low-dropout voltage references manufactured by Analog Devices / Maxim Integrated. The family shares identical pinouts and general electrical characteristics, differing primarily in their fixed output voltage options ranging from 1.25V to 5V. All members utilize the same 8-pin SO package and BiCMOS process technology.

Replacement Considerations

Other members of the MAX6161–MAX6168 series are pin-compatible alternatives if different output voltages are acceptable. Verify that any substitute maintains the required 4.096V output level and meets the specific accuracy and temperature coefficient grades defined in the original design specifications.
