Overview
The MAX6029ESA41+ 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 over 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 dropout voltage of 200mV at full source load. Internal compensation ensures stability with capacitive loads up to 10µF without external components.
Feature Summary
- Ultra-low power consumption suitable for battery-operated systems
- High precision with tight initial accuracy and low drift
- Capable of sourcing significant load current while maintaining regulation
- Internally compensated for stability with large capacitive loads
Applications
- Battery-powered portable instruments
- Precision analog-to-digital and digital-to-analog converters
- Hand-held measurement devices
- Precision power supply references
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 pin configuration and thermal characteristics for the target application environment.
Selection Notes
Select this component when a stable 4.096V reference is required in space-constrained designs using surface-mount technology. Consider the 8.75µA maximum supply current for low-power budgets. Evaluate the 200mV dropout voltage against the minimum available input supply to ensure proper regulation under all operating conditions.
Part Context
This part belongs to the MAX6029 family of ultra-low-power precision series voltage references. The family includes variants in 5-pin SOT23 and 8-pin SO packages with outputs ranging from 2.048V to 5V. The MAX6029 series is designed for applications demanding high accuracy and minimal board space usage compared to traditional SO-package references.
Replacement Considerations
Direct substitutes within the same family include MAX6029EUK41+T (SOT23-5, 4.096V). Other voltage options like MAX6029ESA25+ or MAX6029ESA50+ are available if different reference voltages are acceptable.
