MAX6034BEXR41+T

Overview

The MAX6034BEXR41+T is a precision, micropower, low-dropout series voltage reference housed in a miniature 3-pin SC70 surface-mount package. It delivers a fixed output voltage of 4.096V with an initial accuracy of ±0.4% and a maximum temperature coefficient of 75ppm/°C. The device operates within an extended temperature range of -40°C to +85°C and draws a typical quiescent supply current of 95µA. It supports sourcing up to 1mA and sinking up to 200µA of load current while maintaining stability with capacitive loads ranging from 0 to 1µF without requiring external compensation.

Feature Summary

• Proprietary curvature-correction circuitry combined with laser-trimmed thin-film resistors ensures high precision and low temperature drift.
• Series-mode architecture provides supply current virtually independent of input voltage variations, eliminating the need for external biasing resistors.
• Internally compensated design remains stable with capacitive loads up to 1µF, removing the requirement for external output capacitors.
• Low dropout voltage allows operation at minimal differential voltages between input and output, optimizing efficiency in battery-powered systems.

Applications

• Hand-held equipment
• Data-acquisition systems
• Industrial and process control systems
• Battery-operated equipment
• Hard-disk drives

Procurement Notes

Verify the specific suffix 'B' indicates the ±0.4% accuracy grade rather than the higher precision 'A' variant. Confirm the '41' designation corresponds to the 4.096V output voltage. Ensure the 'EXR' code matches the required SC70-3 surface-mount packaging. Cross-reference the '+T' marking with reel or cut-tape delivery formats as specified by the distributor.

Selection Notes

Select this component when board space is limited due to its compact SC70-3 footprint. Choose this part if the application requires a fixed 4.096V reference with moderate precision (±0.4%) and ultra-low power consumption. It is suitable for designs where eliminating external capacitors simplifies the layout. Consider the 75ppm/°C temperature coefficient against stricter requirements that might necessitate the 'A' grade version.

Part Context

This device belongs to the MAX6034 family of precision, micropower, low-dropout series voltage references manufactured by Analog Devices / Maxim Integrated. The family shares common architectural features including proprietary curvature correction and internal compensation. Variants differ primarily in output voltage options and initial accuracy grades, all utilizing the same miniature 3-pin SC70 package for space-constrained applications.

Replacement Considerations

MAX6034AEXR41+T offers identical electrical characteristics except for improved initial accuracy of ±0.2%.
