MAX6138AEXR33

Overview

The MAX6138AEXR33 is a precision, two-terminal shunt mode bandgap voltage reference manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides a fixed output voltage of 3.0V with an initial accuracy of 0.2% and a temperature coefficient of 25ppm/°C. The device operates within a supply current range up to 15mA and functions across a temperature range of -40°C to +85°C. Packaged in a compact SC-70 surface-mount case, it utilizes laser-trimmed resistors for stability.

Feature Summary

Two-terminal shunt architecture designed for space-critical applications
Laser-trimmed resistors ensure precise initial accuracy
Subminiature SC-70 package reduces footprint significantly

Applications

Portable instrumentation requiring high precision
Battery-powered measurement systems
Data acquisition systems needing stable references

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to limited availability status. Confirm RoHS compliance and specific suffix variations match design requirements. Check lead times as supply may be restricted or subject to factory special orders. Ensure storage conditions meet moisture sensitivity level standards before assembly.

Selection Notes

Select this component when a fixed 3.0V reference is required in minimal board space. Compare against other MAX6138 variants if different voltage outputs like 1.2205V or 2.048V are needed. Consider the 0.2% accuracy grade sufficient for most general-purpose analog circuits. Evaluate thermal management needs given the small package size and shunt operation mode.

Part Context

Part of the MAX6138 family of precision voltage references offering multiple reverse breakdown voltages. Designed to replace larger SOT23 packages with a 50% smaller SC-70 form factor. Manufactured using BICMOS technology for low power consumption and high stability in portable electronic devices.
