MAX6198BESA-TG069

Overview

The MAX6198BESA+T is a precision, micropower, low-dropout voltage reference manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 4.096V with an initial accuracy of ±0.05% and a temperature coefficient of 5ppm/°C. The device operates within an input voltage range of 4.296V to 12.6V and draws a maximum quiescent supply current of 35µA. It supports source and sink currents up to 500µA and functions across a temperature range of -40°C to +85°C. Packaged in an 8-SOIC surface-mount format, it meets AEC-Q100 automotive qualification standards.

Feature Summary

• Features proprietary curvature-correction circuitry and laser-trimmed precision thin-film resistors for high initial accuracy and low temperature drift.
• Offers virtually immune supply current against input voltage variations, ensuring stable performance under varying power conditions.
• Internally compensated design suitable for applications requiring fast settling times without external compensation components.

Applications

• Battery-powered instruments requiring low quiescent current consumption
• Automotive electronic systems meeting AEC-Q100 qualification standards
• Precision analog-to-digital converter (ADC) reference sources

Procurement Notes

Verify the specific suffix 'TG069' against official manufacturer documentation, as standard datasheets typically list 'MAX6198BESA+T'. Confirm availability status, as some distributors indicate limited stock or discontinuation for related variants. Ensure the component matches the required 8-SOIC package and automotive grade specifications before procurement.

Selection Notes

Select this component when a fixed 4.096V reference with high precision (±0.05%) and low noise is required. It is suitable for designs needing low power consumption (35µA) and robust performance in automotive environments. Consider the 500µA load regulation capability and internal compensation for simplified circuit design.

Part Context

This part belongs to the MAX6190–MAX6195/MAX6198 series of precision voltage references. These devices are designed for applications demanding high accuracy and stability. The series utilizes a series-mode bandgap architecture, distinguishing it from shunt references. It is part of Maxim Integrated's portfolio now managed by Analog Devices Inc.

Replacement Considerations

Check for direct substitutes within the MAX6190-MAX6195 family if different output voltages are needed. Verify pin compatibility and electrical specifications against other AEC-Q100 qualified voltage references from Analog Devices or third-party manufacturers.
