MAX6325CSA+

Overview

The MAX6325CSA+ is a low-noise, precision voltage reference utilizing buried-zener technology. It provides a fixed 2.5V output with an initial accuracy of ±0.02% and a maximum temperature coefficient of 1ppm/°C. The device operates within an input voltage range of 8V to 36V and supports load currents up to ±15mA. It features extremely low noise performance, specified at 1.5µVp-p from 0.1Hz to 10Hz. The component is housed in an 8-pin SO package and is rated for operation between 0°C and +70°C.

Feature Summary

• Utilizes buried-zener technology for minimal noise performance
• Offers optional external trimming and noise reduction capabilities
• Guaranteed load regulation for source and sink currents up to 15mA
• Stable for all capacitive loads

Applications

• High-Resolution Analog-to-Digital Converters
• Digital-to-Analog Converters
• High-Accuracy Reference Standards

• Precision Current Sources

Procurement Notes

Verify the specific suffix 'CSA+' against official documentation to confirm the 8-pin SO package and commercial temperature range (0°C to +70°C). Ensure compatibility with existing board layouts by checking pin configurations. Confirm RoHS compliance status through manufacturer certificates prior to integration.

Selection Notes

Select this component when high stability and low noise are critical for data conversion systems. The buried-zener architecture ensures excellent long-term stability. Consider the available trim and noise reduction pins if further optimization beyond factory settings is required for the specific application environment.

Part Context

This part belongs to the MAX6325/MAX6341/MAX6350 family of 1ppm/°C, low-noise voltage references. While the MAX6341 provides 4.096V and the MAX6350 provides 5V, the MAX6325 variant is specifically configured for a 2.5V output. All members share similar electrical characteristics and packaging options.
