MAX6162AESA

Overview

The MAX6162AESA+ is a precision, micropower, low-dropout voltage reference from the MAX6161–MAX6168 series. It provides a fixed output voltage of 2.048V with an initial accuracy of ±2mV and a maximum temperature coefficient of 5ppm/°C. The device operates within an input voltage range of 2.5V 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 compensation capacitors.

Feature Summary

• Proprietary curvature-correction circuitry ensures high stability across temperature variations.
• Laser-trimmed thin-film resistors contribute to precise initial accuracy and low drift.
• Supply current remains virtually independent of input voltage changes.
• Internal compensation eliminates the need for external frequency-stability capacitors.

Applications

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

Procurement Notes

Verify the specific suffix 'A' indicates the ±2mV initial accuracy and 5ppm/°C temperature coefficient grade. Confirm the package type matches the required SO-8 footprint. Ensure the application input voltage stays within the 2.5V to 12.6V operational range to maintain specified line regulation performance.

Selection Notes

Select this component when a stable 2.048V reference is needed with minimal board space due to the lack of external capacitor requirements. Consider the 100µA quiescent current for battery life calculations. Verify that the load current does not exceed the 5mA sourcing or 2mA sinking limits defined in the electrical characteristics.

Part Context

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

Replacement Considerations

Other members of the MAX6161–MAX6168 series may serve as functional replacements if different output voltages are acceptable. Ensure the substitute maintains the required accuracy grade and package compatibility.
