MAX6138AEXR41-T

Overview

The MAX6138AEXR41-T is a precision shunt voltage reference manufactured by Analog Devices under the Maxim Integrated brand. It provides a nominal output voltage of 4.096 V with an initial accuracy of 0.2% and a temperature coefficient of 25 ppm/°C. The device operates within a supply current range up to 15 mA and functions reliably across an extended industrial temperature range from -40°C to +85°C. Packaged in a compact SC-70-3 surface-mount footprint, it serves as a stable voltage source for high-precision analog circuits.

Feature Summary

• Delivers precise shunt voltage regulation with tight initial accuracy specifications
• Maintains stability over wide temperature variations using low drift technology
• Utilizes a miniature three-terminal SC-70 package for space-constrained designs

Applications

• Portable instrumentation requiring stable reference voltages
• Battery-powered measurement systems
• Data acquisition channels

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm specific suffix designations match exact electrical tolerances and packaging requirements. Request original datasheets and lot traceability documentation prior to procurement to ensure compliance with quality standards and application specifications.

Selection Notes

Select this component when a fixed 4.096 V reference is required in minimal board space. Ensure the shunt topology suits the circuit ground connection needs. Verify that the 25 ppm/°C drift meets system thermal stability requirements. Check that the operating current remains within the specified maximum limits during all operational phases.

Part Context

This part belongs to the MAX6138 series of two-terminal voltage references designed for precision applications. The series offers various fixed output voltages and accuracy grades. The A-grade variant specifies tighter initial accuracy compared to standard versions. The E suffix indicates the SC-70-3 package type suitable for automated surface-mount assembly processes.

Replacement Considerations

Cross-reference with other MAX6138 variants offering different voltage outputs or accuracy grades if electrical parameters require adjustment. Verify pinout compatibility before substituting with similar SC-70 shunt references from other manufacturers.
