MAX6034AEXR41+T

Overview

The MAX6034AEXR41+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 ±0.2% and a maximum temperature coefficient of 30ppm/°C. The device operates within an input voltage range of (VOUT + 200mV) to 5.5V, drawing a typical quiescent supply current of 125µA. It can source up to 1mA and sink up to 200µA of load current while maintaining stability with capacitive loads ranging from 0 to 1µF without requiring external compensation components.

Feature Summary

• Utilizes proprietary curvature-correction circuitry and laser-trimmed thin-film resistors for high precision
• Features ultra-low dropout voltage allowing operation in low-voltage battery-powered applications
• Supply current remains virtually independent of the input supply voltage
• Internally compensated design eliminates the need for external frequency-stability capacitors

Applications

• Hand-Held Equipment
• Data-Acquisition Systems
• Industrial and Process Control Systems
• Battery-Operated Equipment
• Hard-Disk Drives

Procurement Notes

Verify the specific suffix 'A' indicates the ±0.2% accuracy grade and '41' denotes the 4.096V output voltage during procurement. Confirm the '+T' designation corresponds to the reel packaging format required for your assembly line. Ensure the component meets RoHS compliance standards as specified by the manufacturer for environmental regulations.

Selection Notes

Select this component when board space is critical due to its compact SC70-3 footprint. It is suitable for designs requiring stable references that do not necessitate external compensation capacitors. Consider the 125µA supply current and 4.096V output level against system power budgets and ADC/DAC requirements.

Part Context

This part belongs to the MAX6034 family of precision bandgap references manufactured by Analog Devices / Maxim Integrated. The family shares common architectural features including low dropout characteristics and micropower consumption, differentiated primarily by output voltage options and accuracy grades available in the same SC70 package.

Replacement Considerations

Compatible substitutes within the same family include MAX6034BEXR41+T, which offers ±0.4% accuracy instead of ±0.2%. Other voltage variants such as MAX6034AEXR33+T or MAX6034AEXR25+T share identical pinouts and electrical characteristics except for the fixed output voltage level.
