MAX6198BESA

Overview

The MAX6198BESA+T is a precision, micropower, low-dropout series-mode bandgap voltage reference. It provides a fixed output of 4.096V with an initial accuracy of ±5mV and a maximum temperature coefficient of 5ppm/°C. The device draws a maximum quiescent supply current of 35µA and supports source/sink currents up to 500µA. It operates within a supply voltage range of 4.296V to 12.6V and features internal compensation for stability with capacitive loads up to 2.2nF.

Feature Summary

• Proprietary curvature-correction circuit combined with laser-trimmed thin-film resistors ensures high initial accuracy and very low temperature drift.
• Micropower architecture with virtually input-voltage-immune supply current maximizes efficiency in battery-powered applications.
• Internally compensated design allows stable operation with capacitive loads up to 2.2nF without requiring external components.

Applications

• Hand-Held Instruments
• Analog-to-Digital and Digital-to-Analog Converters
• Industrial Process Control
• Precision 3V/5V Systems
• Hard-Disk Drives

Procurement Notes

Verify the specific suffix (e.g., +T) against official documentation to confirm packaging type and RoHS compliance status. Ensure the ordering code matches the required automotive or commercial grade specifications. Confirm availability through authorized distributors as stock levels may vary.

Selection Notes

Select this component when a fixed 4.096V reference is required with strict limits on temperature drift and initial accuracy. The low quiescent current makes it suitable for portable devices where power conservation is critical. Verify that the input voltage remains above the minimum dropout threshold for the expected load conditions.

Part Context

This part belongs to the MAX6190–MAX6195/MAX6198 family of precision voltage references manufactured by Analog Devices / Maxim Integrated. The family shares common architectural features including micropower consumption and low-dropout capabilities, differentiated primarily by their fixed output voltage levels and specific accuracy grades.

Replacement Considerations

Consult the manufacturer's selector guide for alternative parts within the MAX619x series offering different output voltages or accuracy grades. Cross-reference with other precision bandgap references if pin compatibility or package constraints require substitution.
