Overview
The MAX6129AEUK41+T is a micropower, low-dropout bandgap voltage reference in a 5-pin SOT-23 package. It provides a fixed output of 4.096V with an initial accuracy of ±0.4% and a maximum temperature coefficient of 40ppm/°C. The device operates within a supply range of 2.5V to 12.6V, drawing a maximum supply current of 5.25µA. 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 ±0.4% initial accuracy and low drift
- Stable operation with capacitive loads up to 10µF without external components
- Miniature surface-mount footprint reduces board space requirements
Applications
- Battery-powered systems
- Handheld instruments
- Precision power supplies
- A/D and D/A converters
Procurement Notes
Verify the specific suffix 'EUK41' confirms the 4.096V output voltage and 'A' grade indicates the ±0.4% accuracy level. Ensure the '+T' designation matches the required reel packaging format. Confirm the manufacturer is Analog Devices Inc./Maxim Integrated to guarantee component authenticity and datasheet alignment.
Selection Notes
Select this part when a stable 4.096V reference is required in a compact SOT-23-5 form factor. It is suitable for applications demanding low power consumption and high accuracy over a wide temperature range. Consider the 4mA sourcing capability and stability with capacitive loads when designing the output stage.
Part Context
This component belongs to the MAX6129 series of ultra-low-power series voltage references. The family offers various fixed output voltages including 2.048V, 2.5V, 3V, 3.3V, and 5V. The 'A' grade denotes tighter initial accuracy specifications compared to the standard 'B' grade variants within the same package type.
Replacement Considerations
Direct substitutes include other MAX6129 variants with different output voltages or grades, such as MAX6129BEUK41+T (±1% accuracy) or MAX6129AEUK33+T (3.3V output). Cross-family replacements require verification of pin compatibility and electrical parameter alignment.
