Overview
The MAX6061BEUR+T is a precision, micropower voltage reference featuring a fixed 1.248V output in a 3-pin SOT-23 package. It delivers ±0.32% initial accuracy and a maximum temperature coefficient of 20ppm/°C. The device operates within an input voltage range of 2.5V to 12.6V, drawing a typical quiescent supply current of 90µA. It supports sourcing up to 5mA and sinking up to 2mA of load current while maintaining stability without requiring external compensation capacitors.
Feature Summary
- Proprietary curvature-correction circuit with laser-trimmed thin-film resistors for high precision
- Ultra-low dropout voltage enabling operation in battery-powered systems
- Internally compensated design eliminates the need for external frequency-stability capacitors
Applications
- Analog-to-Digital Converters (ADCs)
- Portable Battery-Powered Systems
- Precision 3V/5V Systems
Procurement Notes
Verify the specific suffix 'B' indicates the ±0.32% accuracy grade rather than the standard ±0.4% variant. Confirm the '+T' designation corresponds to tape-and-reel packaging as specified in the ordering information. Ensure the component meets RoHS compliance requirements for your assembly process.
Selection Notes
Select this part when board space is limited due to its compact SOT-23-3 footprint. Choose this model over shunt references to maximize efficiency, as supply current remains virtually independent of the input voltage. Consider the low noise specifications if the application requires high signal integrity in sensitive measurement circuits.
Part Context
This component belongs to the MAX6061–MAX6068 family of precision, low-dropout, micropower voltage references manufactured by Analog Devices / Maxim Integrated. The series utilizes BiCMOS technology and offers various fixed output voltages ranging from 1.25V to 5V within the same physical package form factor.
Replacement Considerations
Direct substitutes within the same accuracy grade include the MAX6061AEUR+T. Other family members such as the MAX6062 or MAX6066 share identical pinouts and electrical characteristics but provide different fixed output voltages.
