Overview
The MAX6012BEUR-T is a precision series-mode voltage reference from Analog Devices, packaged in a surface-mount SOT-23-3. It delivers a nominal output of 1.247V with an initial accuracy of ±0.48% and a maximum temperature coefficient of 30ppm/°C across the -40°C to +85°C range. The device draws a quiescent supply current of 35μA maximum and supports up to 500μA of source or sink load current. It operates within a supply voltage range of 2.5V to 12.6V.
Feature Summary
- Proprietary curvature-correction circuitry ensures low temperature drift and high initial accuracy
- Micropower operation with supply current virtually independent of input voltage variations
- Internally compensated design eliminates the need for external compensation capacitors
- Capable of sourcing and sinking load currents while maintaining stability
Applications
- Hand-Held Equipment
- Data Acquisition Systems
- Industrial and Process-Control Systems
- Battery-Operated Equipment
- Hard-Disk Drives
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm that the 'B' grade meets the required ±0.48% accuracy specification for your application. Ensure the input voltage remains within the 2.5V to 12.6V range to maintain guaranteed line regulation performance.
Selection Notes
Select this component for applications requiring a stable 1.247V reference in space-constrained designs. The SOT-23-3 package minimizes board area usage. Consider the 30ppm/°C temperature coefficient if operating across wide thermal ranges. Verify that the 500μA drive capability suffices for downstream circuit loads.
Part Context
This part belongs to the MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/MAX6045/MAX6050 family of precision, low-power, low-dropout voltage references. All members share identical pinouts and general characteristics, differing primarily in their fixed output voltages and slight variations in noise and dropout specifications.
Replacement Considerations
Other members of the MAX6012 family (e.g., MAX6021, MAX6025) are pin-compatible but provide different output voltages. Direct substitutes must match the 1.247V output requirement.
