MAX6029ESA41+T

Overview

The MAX6029ESA41+T is a micropower, low-dropout bandgap voltage reference in an 8-pin SO package. It provides a fixed output of 4.096V with ±0.15% initial accuracy and a maximum temperature coefficient of 30ppm/°C. The device operates within a supply range of 4.3V to 12.6V, drawing a maximum supply current of 8.75µA. It sources up to 4mA and sinks up to 1mA of load current, featuring a low dropout voltage of 200mV at full source current.

Feature Summary

• Ultra-low quiescent supply current for extended battery life
• High precision with ±0.15% initial accuracy and low drift
• Internal compensation ensures stability without external capacitors
• Capable of sourcing 4mA and sinking 1mA load currents

Applications

• Battery-powered systems
• Hand-held instruments
• Precision power supplies
• A/D and D/A converters

Procurement Notes

Verify the specific suffix 'ESA41' corresponds to the 8-pin SO package and 4.096V output variant. Confirm RoHS compliance status indicated by the '+' symbol. Ensure the ordering code matches the required lead-free specification for your manufacturing process requirements.

Selection Notes

Select this component when board space constraints favor an 8-pin SO package over the available SOT-23 option. Choose this part if the system requires a 4.096V reference with high precision and low power consumption. Verify that the input voltage remains above the minimum requirement of 4.3V to ensure proper regulation.

Part Context

This device belongs to the MAX6029 family of ultra-low-power precision series voltage references. The family includes variants with different output voltages (2.048V, 2.5V, 3V, 3.3V, 5V) and packages (SOT-23, SO). All variants share similar electrical characteristics regarding accuracy, temperature coefficient, and low power consumption.

Replacement Considerations

Compatible substitutes include other MAX6029 variants such as MAX6029ESA25+ or MAX6029ESA50+, provided the output voltage difference is acceptable for the application.
