MAX6341CSA

Overview

The MAX6341CSA+ is a precision voltage reference IC from the MAX6325/MAX6341/MAX6350 family, manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 4.096V with an initial accuracy of ±0.02%. The device utilizes buried-zener technology to achieve ultra-low noise performance and extremely low temperature coefficients, with a maximum value of 1ppm/°C in the commercial grade. It supports input voltages ranging from 8V to 36V and offers load regulation for source and sink currents up to 15mA. The component is housed in an 8-pin SO package and operates within a temperature range of 0°C to +70°C.

Feature Summary

• Features industry-standard pinout compatible with other devices in the series
• Supports optional external trimming and noise reduction capabilities
• Maintains stability across all capacitive loads without oscillation

Applications

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

Procurement Notes

Verify the specific suffix 'CSA' corresponds to the commercial temperature range (0°C to +70°C) and 8-pin SO package configuration as defined in the official ordering information. Confirm RoHS compliance status through current manufacturer documentation, as environmental certifications may vary by production batch. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the Analog Devices product.

Selection Notes

Select the MAX6341CSA+ when a stable 4.096V reference is required for high-resolution data conversion systems up to 16 bits. This part is suitable for designs needing low power consumption and excellent transient response. Consider the MAX6341EPA or MAX6341ESA if operation outside the commercial temperature range is necessary. Evaluate the need for external trimming or noise reduction features based on specific circuit requirements before finalizing the component choice.

Part Context

The MAX6341CSA+ belongs to the MAX6325/MAX6341/MAX6350 family of 1ppm/°C, low-noise voltage references. These devices share identical pinouts and functional characteristics, differing primarily in their fixed output voltages: 2.5V, 4.096V, and 5V respectively. All variants utilize the same buried-zener architecture and offer similar performance metrics regarding temperature coefficient, noise, and long-term stability, allowing for flexible design integration across various precision applications.

Replacement Considerations

Direct replacements within the same family include the MAX6341EPA and MAX6341ESA for extended temperature ranges. Cross-family substitutes are not explicitly confirmed in the provided datasheet; verify compatibility with alternative manufacturers only through independent technical validation.
