Overview
The MAX6035BAUR25+T is a high-voltage, precision micropower voltage reference in a 3-pin SOT-23 package. It provides a fixed 2.5V output with an initial accuracy of ±0.5% and a maximum temperature coefficient of 65ppm/°C from -40°C to +85°C. The device operates over a wide supply voltage range up to 33V, drawing a typical quiescent current of 73µA. It can source 10mA or sink 2mA of load current without requiring external compensation capacitors.
Feature Summary
- Proprietary curvature-correction circuit for low temperature drift
- Laser-trimmed thin-film resistors ensure high initial accuracy
- Internally compensated design eliminates need for external capacitors
- Supply-independent operation maximizes efficiency in battery systems
Applications
- 4mA to 20mA Industrial Control Loops
- Li+ Battery Chargers
- 12-Bit A/D and D/A Converters
- Digital Multimeters
- Portable Data-Acquisition Systems
Procurement Notes
Verify the specific suffix 'B' indicates the 0.5% accuracy grade rather than the standard 0.2% grade found in the 'A' variant. Confirm the '+T' designation aligns with the required reel packaging format. Ensure the component meets RoHS compliance standards as specified by Analog Devices for this series.
Selection Notes
Select this part when a 2.5V reference is needed with moderate precision (±0.5%) and lower cost constraints compared to the higher-grade 'A' version. It is suitable for applications where the wider temperature coefficient of 65ppm/°C is acceptable within the operating environment. Consider the SOT-23 package size for space-constrained designs.
Part Context
This component belongs to the MAX6035 family of high-supply-voltage precision voltage references. It serves as a compact upgrade for industry-standard devices like the REF02 and REF43, offering significantly lower power consumption and a reduced footprint. The family includes options for 2.5V, 3.0V, and 5.0V outputs in both SOT-23 and SO packages.
Replacement Considerations
Direct replacements include other MAX6035 variants such as MAX6035AAUR25+T for tighter accuracy or MAX6035BAUR30+T for different voltage needs. Cross-family alternatives like REF02 or REF43 may require external components and larger PCB area.
