MAX6225ACSA

Overview

The MAX6225ACSA is a low-noise, precision voltage reference utilizing buried-zener technology. It provides a fixed output of 2.500V with an initial accuracy of ±0.02% and a maximum temperature coefficient of 2.0ppm/°C. The device operates within an input voltage range of 8V to 36V and supports source/sink currents up to 15mA. It features a supply current of approximately 2.7mA 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 laboratory-standard temperature stability
• Supports load regulation for both sourcing and sinking currents up to 15mA
• Allows for optional external voltage trimming and wideband noise reduction

Applications

• High-resolution analog-to-digital converters
• Digital-to-analog converters
• High-accuracy industrial process control systems
• Precision digital voltmeters
• Automatic test equipment

Procurement Notes

Verify the specific suffix 'CSA' indicates the SOIC-8 package and 'A' grade corresponds to the 0°C to +70°C operating range. Confirm RoHS compliance status via the '+' designation in the ordering information. Ensure the application circuit matches the required input voltage range and load conditions specified in the datasheet electrical characteristics.

Selection Notes

Select this component when high resolution data conversion requires minimal drift and low noise. The buried-zener architecture ensures superior long-term stability compared to bandgap references. Consider the available trim pin for fine-tuning output voltage if system tolerances demand adjustments beyond the factory-set accuracy.

Part Context

This part belongs to the MAX6225/MAX6241/MAX6250 family of precision voltage references. While the MAX6241 outputs 4.096V and the MAX6250 outputs 5.000V, the MAX6225 is specifically configured for a 2.500V output. All devices share identical pinouts and feature sets, differing primarily in their nominal output voltages.

Replacement Considerations

Direct replacements include other variants within the MAX6225 series such as MAX6225BCSA+ or MAX6225AEPA+, depending on required temperature ranges and accuracy grades.
