MAX6250ACPA+

Overview

The MAX6250ACPA+ is a low-noise, precision voltage reference featuring buried-zener technology. It provides a fixed 5.000V output with ±0.02% initial accuracy and a maximum temperature coefficient of 2.0ppm/°C. The device operates within an input voltage range of 8V to 36V and draws a supply current of 3.3mA. It supports source and sink currents up to 15mA and offers optional external trimming and noise reduction capabilities.

Feature Summary

• Utilizes buried-zener technology for extremely low noise performance
• Provides excellent initial accuracy and high temperature stability
• Supports both sourcing and sinking load currents up to 15mA
• Allows for optional external voltage trimming and noise reduction

Applications

• High-resolution analog-to-digital and digital-to-analog converters
• High-accuracy industrial and process control systems
• Digital voltmeters and ATE equipment
• Precision current sources

Procurement Notes

Verify the specific suffix 'CPA+' indicates an 8-pin Plastic DIP package and RoHS compliance. Confirm the 'A' grade designation matches the required 2.0ppm/°C temperature coefficient limit. Ensure the operating environment falls within the specified 0°C to +70°C range for this variant.

Selection Notes

Select this component when a fixed 5V precision reference is required with minimal drift. Consider the buried-zener architecture for superior low-frequency noise characteristics compared to bandgap references. Evaluate the need for external trim or noise reduction features based on system sensitivity requirements.

Part Context

This part belongs to the MAX6225/MAX6241/MAX6250 family of low-noise, precision voltage references. While sharing identical pinouts and core technologies, it is distinguished by its fixed 5.000V output setting. Other family members provide 2.5V or 4.096V outputs.

Replacement Considerations

Direct replacements within the same series include MAX6250BCPA+ (higher tempco) or MAX6250AEPA+ (extended temperature range). Verify package compatibility and thermal specifications when substituting.

FAQ

How can the output noise be reduced?

Add a 1μF capacitor between the NR pin and ground to augment wideband noise reduction.

Is the device stable with capacitive loads?

Yes, the MAX6250ACPA+ is stable with capacitive load values ranging from 0μF to 100μF.
