MAX6034BEXR25

Overview

The MAX6034BEXR25 is a precision micropower voltage reference IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It provides a fixed output voltage of 2.5V with an initial accuracy of ±0.4%. The device operates within an input voltage range of 3.2V to 5.5V and draws a supply current of 125µA maximum. It features a low temperature coefficient of 75ppm/°C and supports a maximum load current of 1mA. The component is housed in a compact SC-70-3 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Delivers stable, fixed 2.5V output for high-precision analog signal conditioning
• Optimized for battery-powered systems through ultra-low micropower consumption
• Ensures measurement consistency over varying thermal conditions via low drift characteristics

Applications

• Portable medical instrumentation requiring precise voltage standards
• Data acquisition systems utilizing analog-to-digital converters
• Battery-operated test and measurement equipment

Procurement Notes

Verify the specific suffix 'B' indicates the required accuracy grade and 'EXR' confirms the SC-70-3 tape-and-reel packaging configuration. Confirm that the '+T' designation aligns with RoHS compliance requirements for your manufacturing process. Ensure the input voltage supplied to the circuit remains within the specified 3.2V to 5.5V operational window to maintain regulation integrity.

Selection Notes

Select this component when a small form factor is critical alongside moderate precision requirements. It serves as a suitable alternative to larger packages if board space is constrained. Consider the 1mA output drive capability against the load requirements of the downstream circuitry to ensure adequate performance without exceeding the maximum current limits defined in the datasheet.

Part Context

This part belongs to the MAX6034 series of micropower voltage references designed for applications demanding low power usage and compact sizing. The series integrates bandgap reference technology to provide stable outputs in minimal footprint packages. It targets industries where power efficiency and size reduction are primary design drivers, such as wearable electronics and handheld sensors.

Replacement Considerations

MAX6034BEXR30+T: Offers identical electrical specifications and packaging but provides a fixed 3.0V output instead of 2.5V.
