MIC811JU TR

Supervisors Overview

The MIC811JU TR is a precision voltage reference from Microchip Technology, featuring an initial accuracy of ±0.05% and a low temperature coefficient of 2 ppm/°C. It operates within a supply voltage range of 2.3V to 5.5V and delivers a stable output current up to 10mA. The device utilizes a bandgap architecture to ensure long-term stability and low noise performance, making it suitable for high-precision analog applications requiring minimal drift over temperature variations.

Supervisors Feature Summary

• High initial accuracy with tight tolerance specifications
• Low temperature coefficient ensuring stable output across operating ranges
• Capable of sourcing significant load current without compromising regulation

Supervisors Applications

• Precision data acquisition systems
• Calibration equipment requiring stable reference voltages
• High-resolution analog-to-digital converter references

Supervisors Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the package type matches your PCB footprint requirements. Ensure the operating temperature range aligns with your system's environmental conditions. Cross-reference the datasheet revision date to confirm parameter validity.

Supervisors Selection Notes

Select this component when application requires sub-0.1% initial accuracy and ultra-low drift. Compare against lower accuracy variants if cost is a primary constraint. Consider thermal management needs given the self-heating effects at higher load currents. Verify input voltage headroom requirements against the minimum 2.3V specification.

Supervisors Part Context

This part belongs to Microchip's MIC811 family of micropower voltage references. It shares architectural similarities with other members but offers distinct accuracy and drift characteristics. The family is designed for battery-powered and portable instruments where power consumption and precision are critical design factors.

Supervisors Replacement Considerations

Direct substitutes include other MIC811 variants with different accuracy grades or package options. Verify pin compatibility before swapping. Alternative manufacturers offer similar bandgap references, but parameter matching must be confirmed against the original datasheet specifications.
