Overview
The MAX6041AEUR+T is a precision, low-dropout, micropower series-mode voltage reference from the MAX6012 family. It provides a fixed output of 4.096V with an initial accuracy better than 0.2% and a temperature coefficient under 15ppm/°C. The device operates over an extended temperature range of -40°C to +85°C in a miniature SOT-23-3 package. It draws only 27μA typical quiescent current, independent of supply voltage, and can source or sink up to 500μA load current. Input voltage ranges from VOUT + 0.2V to 12.6V.
Feature Summary
- Proprietary curvature-correction circuit and laser-trimmed thin-film resistors ensure high precision and stability.
- Series-mode architecture eliminates the need for external biasing resistors required by shunt references.
- Internally compensated design remains stable with capacitive loads up to 2.2nF without external components.
- Ultra-low supply current variation of 0.8μA/V maximizes efficiency in battery-operated systems.
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 the 'A' grade designation matches the required 0.2% initial accuracy specification. Ensure the input voltage supply meets the minimum dropout requirement relative to the 4.096V output. Check for RoHS compliance status if environmental regulations apply to the assembly process.
Selection Notes
Select this component when a fixed 4.096V reference is needed with minimal board space due to the SOT-23-3 footprint. It is suitable for applications requiring low quiescent current to extend battery life. Consider the 500μA sourcing and sinking capability for driving moderate loads directly. Verify that the system does not require higher output currents beyond the specified limits.
Part Context
This part belongs to the MAX6012/MAX6021/MAX6025/MAX6030/MAX6041/MAX6045/MAX6050 family of precision voltage references. All members share similar low-power characteristics and packaging but offer different fixed output voltages ranging from 1.247V to 5.000V. The MAX6041 specifically targets applications requiring a standard 4.096V reference level.
Replacement Considerations
Other members of the MAX6012 family (e.g., MAX6025, MAX6030) are pin-compatible alternatives offering different fixed output voltages. Cross-model substitution requires verifying that the new output voltage meets the system requirements while maintaining the same package and electrical performance characteristics.
FAQ
Does the MAX6041AEUR+T require an external compensation capacitor?
No, the device is internally compensated and stable with capacitive loads from 0 to 2.2nF, eliminating the need for an external compensation capacitor.
What is the maximum load current the MAX6041AEUR+T can handle?
The device can source or sink up to 500μA of load current.
How does the supply current of the MAX6041AEUR+T behave with varying input voltage?
The quiescent supply current is virtually independent of the supply voltage, with a variation of only 0.8μA/V across the operating range.
